Shun'ei/Story

Past
Shun'ei is a young boy who is a manipulator of illusions. Due to his mysterious powers, he was abandoned at a young age by his parents. Shun'ei was found and raised as a disciple of Tung Fu Rue. Through his training, Shun'ei learned how to control his powers, formed from his desire to not hurt anyone with them.

The King of Fighters XIV
Prior to the 14th tournament, Tung tells Shun'ei about KOF, the world's largest fighting tournament. Although Shun'ei is less than thrilled to hear about it (since he still isn't sure if he can fight others without his powers fatally harming them), Tung mentions that his former students, Terry Bogard and Andy Bogard, will be attending this year. Additionally, Kyo Kusanagi will be there too, which catches Shun'ei's attention. Shun'ei has heard stories about the Kusanagi heir sealing away a great evil, and wishes to meet him. As Tung's last disciple, he sets out to challenge other fighters from all over the world with his close friend Meitenkun, as Team China.

Throughout the tournament, he meets several fighters, all with different backgrounds to come together to fight. Out of all of them, he meets a mysterious hooded figure that seems to heavily dislike him for some strange reason. Team China lost to an unknown Team at some point during the tournament.

During the tournament's climax, a mysterious entity named Verse appeared, attacking the fighters. Shun'ei's powers seemingly resonates with this creature, which causes him to be a target of the entity. Shun'ei fights Verse, with him defeating him. After Verse's defeat, Shun'ei is advised by Kyo to continue his training to keep his powers under control, as several fighters beforehand have done so in the past. Shun'ei agrees and vows to train harder.

The King of Fighters XV
At the request of his old friend Kyo Kusanagi, Benimaru Nikaido is tasked to watch over the series' new protagonists Shun'ei and Meitenkun. As a result, he leaves the Japan Team and replaces the old master Tung Fu Rue. The three form the Fourth Saga's Hero Team, renaming China Team moniker into a team named after Shun'ei, due to the younger model and fighter's nationality. He is also a target of Team Orochi, as his power is the key to reviving Orochi.
