Riku Rei undergoes a certain ritual and joins Temujin’s group. Meanwhile, Suigin encounters a young boy named Takeshi. Apparently he is travelling to get money to help his ailing friend, Mikan, who’s like his older sister. He ends up crashing a martial arts tournament and accidentally drags Suigin and Twin Star with him.
If that's what it takes... 
to save Mikan-neechan!
!إن كان هذا ما يلزم... لإنقاذ ميكان-نيتشان
Wenn ich damit …
Mikan-neechan retten kann!
¡No si con eso puedo salvar a Mikan!
¡No si con eso puedo salvar a Mikan!
C’est pour sauver Mikan
que je le fais !
Se è quello che serve... 
Per salvare Mikan!
Se for para salvar a 
Mikan-neechan, eu aguento!
Если это поможет... спасти Микан!
