-You can't use healing items during battle in the coliseum, rather, you could use regenerative chips instead
-Hair color, red was only shown (but there are other colors)
-Self destruct actually shaves off Kaine's costume! Not even Yoko knew of this
-There's a bonus item (coliseum reward) that can be found in Amazarashi's music video (me edit: Might be a doll? lol)
