Tachibana Haruka (橘はる花

22 years old and fresh out of university, Haru was a star Earth Science pupil at Jounan University, but has little real-world experience. She is hired by GEO as a field geologist, but on her first trip to a site she comes face to face with monsters rising from the earth called Polymorphs. She uses her belt named the FieldSlider to transform into Kamen Rider Crystal and defeat these enemies of mankind.

Haru is incredibly smart but ill-equipped for fighting, so to begin with she relies on Crystal’s raw strength and her own cunning to defeat her enemies. Outside of being Kamen Rider Crystal, she is friendly, curious, and trusting to a fault. She always tries to see the best in people, which can lead to her being gullible. She’s also very failmoe, and tends to forget her basic needs if she’s dedicated to doing something.
