A second-year at Kyoto Metropolitan Curse Technical College. Kasumi is a hard-working, restrained, and considerate pacifist. She is also a big fan of Satoru Gojo. ~!She has a very close bond with Mechamaru, their friendship is first seen in the Tournament Arc when Miwa offers him a battery telling him not to eat it as Mai and Momo laugh in the background. In the Shibuya Arc, she is seen mourning his death on the train. Over the course of the Tournament Arc and Shibuya Arc it is very apparent their friendship grows as they both strived towards becoming closer to one another. As she mourns his death on the train she holds a mini Mechamaru speaker which tells her to find her happiness. After the recording finishes, she holds the speaker to her heart and cries. The entire Kyoto program seems very distressed by his death on the train. When later entering the battle Miwa is quick to activate her technique out of rage and sadness towards Mahito.!~
