Toaru Kagaku no Railgun: PSP SS
Kohina was one of the four White Alligator members hired to transport the comatose Saitou Souta while Misaka Mikoto and Aizono Mio were distracted by a rumour leading them into a trap, though she and the others had the secret goal of getting revenge on Souta and Mio, jealous of her being the only White Alligator member saved by the counselor. Kohina, Hyoudou Maki and Yoake Sayori faced Aizono Mio in combat while Sakasama Yuri made sure Mikoto asphyxiated in their oil trap, but despite managing to corner her and almost killing her, the trio were defeated by Mio once Mikoto relayed to her Souta's message and intentions of saving all White Alligator members.

Abilities
Her ability is Military Oil (油性兵装 (ミリタリーオイル) ), which allows her to control oil and other petroleum products as well as freely change their properties.

Quotes

 * (To Aizono Mio, Railgun PSP SS): "Did he just grow sick of it all? He may have been satisfied after having some fun, but surely his collector’s spirit would have been telling him to continue on. If you’re going to do something, lick the bones clean. Just picking at it a bit and calling it quits is rude to the cook and to the people who don’t have enough to eat."
