User:Stardustdragon123/Toshiki Kai (Stand Up, the LRIG!)

Toshiki Kai was one of the main protagonists of the Cardfight!! Vanguard Anime and Manga, one of the main antagonists of the Link Joker arc and the main protagonist of the crossover fic, Stand Up, the LRIG!

Appearance
When Kai first came to the world of Wixoss, he had initially arrived in his Hitsue High uniform; despite having previously graduated at the end of Legion Mate.

At the end of his second day in that world, he dons clothes identical to one of his three appearances in the film, Neon Messiah. This one consisted of him wearing a pair of black trousers, a dark red short sleeved shirt and a light brownish jacket with a darker brown present on the shoulder portions.

Personality
Despite remaining aloof to a large extent and remaining cautious of the many Selectors in the new world around him, Kai still retains some of the openness he displayed in Legion Mate to his friends and to people he knows he can trust. Despite initially being confused by Tama when they first met, he agreed to help her, along with Hitoe and Yuzuki find Ruko after learning about what little they knew of the truth of the Selector Battles from the new red LRIG's experiences.

After almost losing to Ruko and Yuki for the first time and coming to terms with the fact that Reverse had not left him after the end of one of his previous fights with Aichi as they had initially presumed, he becomes concerned that a single mistake of carelessness on his part could lead to him committing the same actions that he did in the past. When Noriko calls him out on his sudden cowardice in regards to this subject, despite having no prior knowledge of his previous allegiance at the time, he eventually regains his resolve as he discovers he can use the Seed fragment embedded within him to keep the power at bay whilst also accepting that even if he doesn't use it, it will always be a part of him for life.

Stand Up, the LRIG! Bio (Updated as the story continues)
'The following paragraphs contain spoilers to Stand Up, the LRIG! If you don't want to be spoiled, please read the crossover fic from the beginning.'

Arc 1
Some time after the events of Legion Mate, after graduating fully from Hitsue High School in his world, Kai was accidentally brought into the world of Wixoss by Takuto Tatsunagi (who intended to summon Aichi to his aid instead), not regaining consciousness until he discovered that he was on a hill outside of that world's version of Tokyo. After wandering down to the city streets, he overheard talk of the Selector Battles amongst several of the girls he passes by, not showing any interest in them until he passes by Yuragi and Mako, briefly hearing the voice of Alfou without knowing who the LRIG actually was. After hearing the voices of more LRIGs as he continues to explore his surroundings, he unknowingly wanders towards the incomplete Daikichi Apartments, feeling as if something is drawing him inside, unaware that he is briefly being watched by Ulith during his trek inside and discovering more of the Wixoss card game and the fact that his deck has changed to suit its rules.

Upon making his way to the rooftop, he notices a card glowing and falling from the sky towards him. Catching it, he can see that he now holds the LRIG Tama who is initially confused by the fact he can see her. After introducing themselves to each other, Tama grows worried and requests for Kai to bring her to Ruko to which he accepts, initially believing he can use this opportunity to find out exactly what is going on around him. After wandering around the city with no luck, he encounters Hitoe who accidentally runs into his back before hurrying away. When Tama tells him she is a friend of Ruko, he calls out to her, almost frightening the Selector until he shows the LRIG to her. When Yuzuki asks about the commotion going on, she is shown by Hitoe to Kai and surprised by the fact that he can see both her and the LRIG he currently holds.

The two of them then begin to tell him about all of their experiences in the Selector Battles and what had happened to Ruko after 'Iona' had become her LRIG, leaving Tama upset by what she had done. Upon realizing that the circumstances of these 'Selector Battles' were more dangerous than he presumed before meeting them, Kai agrees to help both Yuzuki and Hitoe find Ruko together. He then quickly shoves Hitoe out of the way of a sharp knife thrown in their direction, before discovering their attacker is Aoi Akira who did not have her wish tainted as Yuzuki and Ruko initially believed. Upon discovering she desires to battle Hitoe again, Kai takes out his Kagero deck and steps in to take her place, using the fact that he can see Tama as a 'means' of making himself an eligible candidate for the Selector Battles.

Piruluk speaks out from her card to make it clear that she would accept the conditions and so would Akira, much to the latter's displeasure. After she opens the battlefield, Tama appears beside Kai's deck as she is not being used in battle, telling him everything on how the battles begin. As the battle progresses, taking advice from Tama in following his first time with the rules of Wixoss and discovering that several of his units can be summoned from Cray to the battlefield as 'LRIGs' under the Kagero clan name as an LRIG Type, Kai takes advantage of a misplay on Akira's end of the battlefield and defeats Piruluk on his 'Final Turn'. Upon exiting in victory, he hoists her by the arm and crushes her knife's blade under the heel of his shoe, demanding she leaves him and the others alone to which she reluctantly obliges.

After returning Hitoe home in the midst of the chaos, Kai then tries to call Miwa and Ren respectively, having failure on either front whilst not knowing he is in a different world. As it is too late for him to seek refuge in the middle of the night, he goes to sleep on the park bench, pondering over everything that has happened so far. He has a nightmare of Link Joker being unleashed upon the world he is now amongst, before coming face to face with a creepy form of Tama who advances maliciously towards him. When he wakes up, he keeps the details of the nightmare from Tama herself before heading back into the streets for breakfast, thankful that his allowance's currency is the same as the world he comes from.

He then meets with Hitoe and Yuzuki later, explaining everything about his units existing in both the game of Cardfight!! Vanguard and the Planet Cray itself and confirming that this world is not the same as the one that he comes from. He briefly outlines his past experience with Link Joker to them, worrying Tama that something similar might be happening with Ruko thanks to Iona being her LRIG. Hitoe then takes him over to Card Luck where he finds a box containing more Kagero units and builds a backup deck around Vortex Dragon during his time there. They then encounter Chiyori and Eldora with the young Selector being excited as ever and not concerned of the consequences for making her wish come true, if only because of it being outlined in a novel she had been reading.

Upon seeing that Kai can interact with Eldora, much to her initial confusion at first, Chiyori then challenges him to a Selector Battle. Kai declines, feeling that she is in need of practice much like himself, to which she reluctantly agrees to take it into a casual game. Despite going in strong, Chiyori loses to him due to Vortex Dragon clearing out her board before the 'Final Turn'. After the battle concludes, he then gazes towards the stairway of Card Luck, feeling as if he was being watched earlier, unaware that Futase and Anne were observing him. Kai and Hitoe then exchange phone numbers to keep in contact with one another in the event any of them learn new information in regards to Ruko or her current whereabouts.

He then rents out a single bedroom apartment which coincidentally is in the same building that Ruko's own apartment is housed in. He decides against visiting her relatives, feeling his presence would only draw suspicion towards himself in regards to her disappearance. After deciding with Tama to talk with Dragonic Overlord in a battlefield as soon as possible, the two of them encounter Chiyori again the following morning, discovering that she managed to obtain a Quintet Wall from the Aqua Force clan and that she briefly encountered Ruko on the night that she disappeared, though neither she or Eldora knew of where she was going at the time.

Some time later, he meets with Hitoe and Yuzuki who request to conduct a practice battle between them in the event her Selector needs to battle her way out of a dangerous situation. During the battle, they are briefly watched by Ruko herself who retreats out of sight after 'Iona' almost gives her away to Yuzuki. Kai emerges victorious in the battle and hands some of his spare Kagero units that were turned into SIGNI to Hitoe, feeling she would make better of use of them with some practice. As he is leaving the library, Ruko watches him from afar, questioning why he is agreeing to help Tama after what she did.

In their search for the Selector, Kai comes across two Selectors who are frozen in a sleeping like state, to which Tama explains that a battle is in progress. Realizing he can enter to watch from the sidelines, he uses her card to enter the field, ending up in one of the towers in the background. Using his cards, he summons Dragonic Overlord from Cray to question it on how it was able to appear in his battle with Akira along with Undeux, Bahr and Nehalem. The dragon itself replies that it does not know itself, even after being questioned by Blaster Blade himself before it then takes a slight interest in Tama, noting her potential as an LRIG herself. After leaving the field on the battle's conclusion, also obtaining four copies of Dragonic Overlord the End as a result, he is watched by Ulith and Akira who now holds Milulun as her new LRIG.

The very next day, he and Tama are then ambushed by several members of Akira's fanclub who are determined to make him pay for tainting her wish and making her lose Piruluk because of it. He gives them one warning to back away as they don't know the true dangers of the Selector Battles, to no avail though. Before he can battle them, Futase approaches the group with the intention of talking to him with the girls also turning their attention to her for 'interfering'. The two of them agree to join forces as they battle onwards, just as Hitoe and Yuzuki arrive to witness the 'Final Turn' to his last battle of the group, also tainting that Selector's wish as a result.

After introducing herself to the group, Futase asks Kai of the units he commands of the Planet Cray as well as changed 'prophecy', that being the series of words etched on the bottom of every Wixoss card backing. After confirming what some of the changed words mean, Futase advises him to read the Wixoss novels she wrote for more clues in understanding what is going on before leaving him alone. After Hitoe and Yuzuki leave him to search for Ruko, Kai is then confronted by Ulith who points him and Tama to the Selector's current whereabouts before leaving him alone.

He later meets with Hitoe and Yuzuki to discuss what he has learned and the three of them along with Tama decide to head to the incomplete Daikichi Apartments, deciding to take caution with Ulith's words as a result. When they discover that Ruko is present at the rooftop along with her LRIG 'Iona', he questions her on her actions to run away from not just her friends, but her family as well. She responds by saying that she didn't want any of them involved in what was happening in any way and then sorely outlines her belief that all of this was caused by Tama when she refused to conduct the oath to become an Eternal Girl and make her wish on setting everyone free come true.

Before she can battle him, Hitoe steps out onto the rooftop with Yuzuki and tries to reason with her to no avail, with Ruko saying that she can't believe them as they believe in Tama. Realizing that a battle may be the only way to knock some sense into her and find out Tama's reasoning for not conducting the oath, Kai accepts her challenge and the two are then brought to the battlefield. Despite it going evenly, he grows Dragonic Overlord to 'the End' and attempts a finishing combo with both its Persona Blast and the Red ARTS, One Rule, Two Birds. He fails when one of his attacks sets off a Life Burst to give Ruko Servant D2 to get around the guard restriction properties of the ARTS.

Ruko then grows 'Iona' to Level 5, shocking everyone by not just the new revelation of such a thing, but the fact that Reverse is coursing through both the Selector and the LRIG in her current form. That fact is confirmed for itself when 'Iona's' attack then hits Dragonic Overlord with the power of Reverse resonating with both it and Kai's Seed fragment. Eventually, the power becomes too much for Kai to handle as he becomes 'reversed' and declares 'Final Turn', growing Overlord from 'the End' to "The Яe-birth" and driving Ruko into a corne. Before he can wage his second attack, Tama cries out loud for him to stop, saying that right now, he is doing the exact same thing he could do to their world as he almost did to his own back in the past.

Kai then struggles to break out of Reverse before eventually breaking free of his possession, thanking Tama for bringing him back to his sense. As Dragonic Overlord "The Яe-birth' unleashes its attack before he can stop his command, he realizes that as that attack carries Reverse in itself, Ruko could be fully reversed if it successfully hits. Realizing that 'Iona' is also 'reversed' and that fate would happen to one of them regardless of the outcome now, he decides to end his turn immediately and prepare to accept his failure, further confirmed by the fact that Ruko held another Servant D2 in her hand to guard with, silently apologizing in agony to Tama, Hitoe and Yuzuki.

Before 'Iona' can land her attack however, a surge of energy caused by Naoki's impatience with the teleporter in Kai's world and a power struggle ensuing between Takuto, Mayu and an astral Leon, results in the battlefield collapsing, ending the battle without a victor or loser. After returning to reality, Kai then confirms that Ruko was indeed the true victor regardless of what had happened and vows to return her back to normal the next time they meet. After she leaves everyone, including Eldora and Chiyori who had watched the battle midway through, Kai falls to his kness, realizing that his actions could have been the very thing that had doomed Ruko's fate from the very beginning and screams in agony out to the evening sky.
