Rai

Rai is a minor character from Twilight Town that appears in Kingdom Hearts II. He is a member of the "Twilight Town Disciplinary Committee" led by Seifer, along with Fuu and Vivi. Rai is never seen without Fuu. He originated from Final Fantasy VIII as the character Raijin.

Kingdom Hearts II
Rai is a member of the Twilight Town Disciplinary Committee, along with Seifer, Fuu, and Vivi. The group often causes trouble for Hayner, Pence, and Olette. Rai is personally responsible for the rumor that the steps at Sunset Station count differently up and down, having counted wrong during a visit with Fuu.

On the first day in the simulated Twilight Town, Roxas and company confront the Committee, who have been claiming they stole photographs from people all over town. Rai watches Roxas and Seifer's fight with the rest of the Committee. If Roxas wins, Rai defends Seifer, saying that he's not feeling well; if Seifer wins, Rai taunts the others.

On the third day, Roxas is chased by Dusks into the Sandlot, where the Committee is hanging around. Dusks surround them, but they are suddenly frozen in time. After the Dusks vanish, Rai praises Seifer for driving the Dusks off, and he shouts after Roxas not to forget the Struggle tournament. During the tournament on the fourth day, Rai cheers for Seifer to win. After Seifer is beaten by the fake Vivi, Rai and Fuu follow him from the Sandlot.

Sora, Donald, and Goofy encounter the Disciplinary Committee in the Sandlot after waking up in the real Twilight Town, and when Seifer antagonizes the group, Rai prepares to fight. When Sora and company return to Twilight Town, they find Seifer, Rai, and Fuu in the Sandlot, having been overwhelmed by a swarm of Nobodies. After the swarm is defeated, Seifer gives Goofy his trophy and leaves with Rai and Fuu.

Some time after Xemnas's defeat, Rai cheers Seifer on during a Struggle tournament fight against Hayner.

Kingdom Hearts III
Rai is absent from Twilight Town, though is alluded to by some of the townsfolk. Reportedly, he has accompanied Seifer on his "warrior's journey."

Design
Rai is very tall and muscular for his age. He has tan skin, dark brown eyes, and short black hair with long sideburns. He has the scruff of a goatee on his chin, and several faint markings on each cheek. He wears an orange tank top featuring black and white tribal designs on the chest and two thunderbolts on the upper back, and dark baggy sweatpants bearing red stripes and the number 8 on the hip over wide yellow sneakers. Around his neck, he wears a thunderbolt necklace, and he keeps a white and blue sweatband on each wrist.

Personality
Rai is loud, brash, and tries to exude a manly attitude. He is very loyal to Seifer, and does anything Seifer asks. However, he is not very smart, so he relies on his strength and is easily angered. As part of the Disciplinary Committee, Rai often bullies others, especially Roxas and his friends.

Rai is easily identified by his penchant for ending his sentences with "y'know?", which is noted in Jiminy's Journal.

Origin
Raijin is a character from Final Fantasy VIII. He acts as Seifer's lackey, along with fellow Disciplinary Committee member Fujin. The two of them follow and support Seifer unconditionally, even after Seifer goes rogue and leaves Balamb Garden to serve Sorceress Edea. However, when Seifer resurrects Lunatic Pandora, he and Fujin beg Seifer to stop following this path and return to being their friend.

Raijin often comes off as rather stupid, and he tends to end his sentences with "ya know?"

He is fought by Squall's party as a boss alongside Fujin. He retains his battle stance from these fights in Kingdom Hearts II when several Nobodies attack the simulated Twilight Town, despite not possessing any weapon.

In Kingdom Hearts II, his outfit bears several allusions to his original appearance. His lightning bolt necklace and the bolts on the back of his tank top refer to his namesake and elemental affinity, while the number 8 on his pants may be a reference to the Final Fantasy installment he appeared in.

Trivia

 * Rai is voiced by Kazuya Nakai, who also voiced Wakka in both the original  and the character's original game, Final Fantasy X.
