In the anime Sunako is captured by a gang boss who has fallen in love with her and Kyohei, true to anime form, comes to rescue her. When Kyohei is hurt Sunako jumps into action to save him by beating up the gang boss. What makes this scene funny is that in the anime its done entirely in her chibi form complete with her throwing said gang boss into his mass of faceless mooks causing an explosion and mooks flying everywhere.
Chapter 74: When resting in the nurse's office, Kyohei kisses Sunako. Her response? The usual nosebleed, except so big it splatters the entire room. It becomes so messy Kyohei forces himself to wipe the place clean. While Sunako still lies there unconscious.
