Shun'ei/Story

Past
Shun'ei is a young boy who is a manipulator of illusions. Due to his mysterious powers, the Amplified Specters manifested at a young age, Shun'ei was abandoned by his parents, then found by Tung Fu Rue, or so he initially believed. Through his training under Tung's wing, Shun'ei learned how to control his powers, formed from his desire to not hurt anyone with them.

Because Shun'ei keeps having reoccurring nightmares of being ordered by certain entities to destroy everything in sight and has his powers comes out all the sudden in controlled state when he wakes up, Tung gave him a set of headphones and bandages to properly suppress those powers by envisioning them as containers for his power.

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 powers and backgrounds to come together to fight. Out of all of the fighters, a mysterious hooded figure seemed to heavily dislike him for some strange reason. Shun'ei, along with Team China, lost to a 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
Prior to the fifteenth tournament, Shun'ei once again having a recurring nightmare that had been haunting him. On the next day, Tung tells Shun'ei and Meitenkun that he has no intentions of joining this year's KOF tournament. Although he requested the boys to team up with Kyo, the job was handed over to Benimaru Nikaido, due to the Kusanagi has very important jobs to reform Team Sacred Treasures as a regular team alongside Iori Yagami and Chizuru Kagura, and investigate the Orochi’s seal being suddenly broken again. He is also a target of Team Orochi, as his power may be the key to Verse's power, as well as being the subject of antagonism by Isla, an girl with similar powers to him.

Throughout the tournament, he fights through several fighters, both old and new. At some point during the tournament, he runs into Kukri again, who he suspected that he knew more about the Amp powers which he and Isla inherited. Before getting any information out of him, Kukri tells him off, saying that he wouldn't get it.

Shun'ei and his team won KOF XV. During the brief celebration, Isla loses control of her Amp, and knocking her out. This power manifested into a physical being called Re Verse, and warps the contestants out of reality. During this, Shun'ei temporarly loses control of his Amp, but is suppressed by Meitenkun and Benimaru. After defeating Re Verse, Isla finally awakens as Otoma=Raga is summoned. Dolores states that the only way to truly destroy Otoma=Raga is a co-annihilation between itself and an Amplified Specter user - Shun'ei or Isla. Both of them refuses to be sacrificed, and fights the goddess with all their might, ultimately leading to their victory.

During Otoma=Raga's destruction, it opens a void of nothingness and attempts a last attack to suck in the fighters. It manages to grab Isla, causing Shu'ei to jump inside to save her. With the help of Amanda, Shun'ei save Isla, knocking all of the fighters back to reality, with Shun'ei being crowned the fifteenth winner of The King of Fighters. Shun'ei finally take his headphones off, signifying his growth and control of his Amp.

In the team's ending, Tung reveals to Shun'ei that he wasn't abandoned in the streets and rescued by Tung, but rather left by his parents at the martial arts master's door after the young boy unknowingly destroyed his home when the Amp recently manifested. While Meitenkun suggested for him to return to his parents, Shun'ei believes that he isn't ready just yet, and asks him and Meitenkun to travel the world together, to which Tung approves of. In a post-credits scene, both of them reach a city.
