This manga is complete BS. Probably one of the worst writing in a shounen manga I have EVER come across.
Surprise pregnancy for the lose! Just because the mangaka wants to give an excuse for not featuring a main female character doesn't warrant a terrible plot twist such as third person narration of how Rika is pregnant because she threw up... LAME!
lol, Aeon is great as always. Ikki should bloody rescue Rika-nee; you don't simply desert a woman who had taken care of you Oh! Great only knows how long.
