Prism is a Yuri Genre manga by Higashiyama Shou.
After a one-day romance with a boy named Hikaru during her last year of grade school, Megu went through middle school without romance. Now entering high school, she's ready to move on with her love life. At school, she meets a pretty girl who abruptly gives her a big hug... Hikaru?!
- Big Brother Instinct: When a group of girls and their boyfriends start harrassing Hikaru and Megumi, one grabs Hikaru by the hair. Next thing you know, her brother is on the scene, giving what can be only called a Death Smile. The ass beating he gives them is only implied, though.
- Bi the Way - Megu's teacher cheerfully explains to her that she swings both ways.
- Closet Key - Despite her initial disappointment at Hikaru's gender, Megu is in love by the second chapter, and her enthusiasm only goes up from there.
- Gayngst - Just at the beginning.
- Schoolgirl Lesbians
- Shipper on Deck - Megu's teacher is always happy to help Megu x Hikaru along... See chapter 6, where she leaves an "It's okay to have sex [in my bed] if you want! :)" note and a lesbian porn DVD in her DVD player ("For you two to study!❤) for them.
- Spit Take - When Megu confronts Hikaru during the school trip about her feelings:
Megu: Hikaru... Do you want to have sex with me?
Megu: Uh... I mean... (M-Maybe not the best place to start.)
- Unsettling Gender Reveal - Hikaru's gotten very pretty since Megu last saw her. She helpfully lifts her skirt to Megu to confirm she's a girl.
