Kai Toshiki never really loved anyone.

He didn't before, just never embraced the fact that there were other people around him, and that they mattered.

Until he met Aichi Sendou.

Kai always felt so strange around the nervous bluenette. Just seeing him made Kai force down his smile, and light up his day.

And he would smile too.

His smile was so gentle, and warmed up Kai on the inside, which he thought only his parents could do. But they were dead.

His eyes were angelic, musical, which Kai thought only music could do.

But it didn't.

Aichi was probably the only reason why Kai enjoyed life, why he wanted to live.

Then Aichi embraced Psyqualia.

Kai didn't know what to do. He had dealt with this before, but never successfully. That made Kai even more frustrated.

When he returned Aichi to normal, he had tried to hide his joy, but just a simple smirk came out.

Something no one else could do.

Then there was link joker. Aichi was devastated over Kai, but so were the others. Though they didn't feel the pain like Aichi did.

Kai despaired without Aichi as well. Every time he defeated and reversed a fighter, he felt some darkness enveloping his heart. Something that only a certain light could rid of.

That light was Aichi.

Once Kai was restored to normal and defeated, Aichi showed him that warm, gentle smile that Kai never got sick of.

And he smiled too.

Now Aichi was missing, and the Quatre Knights were preventing. Kai and his mates from reaching Aichi.

His light.

Kai knew he could not defeat the Quatre knights at his level right now. He felt it when he was defeated by Gailliard, and scorched by flames.

But the pain from the flames were not even close to matching up the ache in his heart.

Kai knew that someday, he would get stronger. He would defeat the Quatre Knights, and get his light back.

But for now, he can only pray.
