Tsukasa was your older brother, and you..loathed or loved him. No in between.

He loved doing shows to make you smile, and was extremely dramatic if you got hurt, which was why when you finally joined kakiyama high with him;

He held your hand with such a deadly grip even the world's strongest man wouldn't be able to escape.

"Don't fear, your BIG BROTHER TSUKASA IS HERE!"

He shouted, as if you weren't old enough to handle yourself.

All he did was draw VERY unwanted attention.
