Powers and AbilitiesEdit

Through the surgery Ryuichi gained the power of an ogre-faced spider. This allows him to shoot silk from his fingers. However he can shoot those threads only once which is why he is ranked #70. Also like his fellow Arthropod Type Marcos E. Garcia he is likely to gain a bigger field of vision through his additional eyes. Given his low rank however his actual combat abilities most likely are pretty low.
