Risa

Risa (Japanese: リサ) is a character in Phantasy Star Online 2. She is an ARKS operative infamous for her lust of guns and unhinged personality.

Risa is a class trainer for rangers and gunners

Risa was a humanoid whose photonic manipulation capacity was damaging her body, so she had to be remade into a CAST to keep her alive. She is perhaps one of the earliest CASTs ever made before the process was refined to what ARKS uses now for the change from humanoid to CAST hence her unstable personality.

Risa is an incredibly proficient at marksmanship, it is also revealed in Episode 6 , that unlike the rest of ARKS who relies on their Photons for targeting and detecting enemy presence, she relies solely on her eyesight when fighting. Inbetween the end of Episode 5 and the start of Episode 6, she obtains the Cosmogenic Arm: Hariette the Celestial.
