[MrTerrorist]

Spoiler for c64:

Yarai lives and beat those creatures by ripping one of their claws!

Also, it turns out Segawa hatred of Yarai was because he wrote her a confession letter but ripped her reply letter but it turns out it wasn't Yarai who wrote that letter and Segawa assume it was him because he was at the place where she and the confessor was suppose to meet.
