Kakeru’s childhood friend and one of the few people that supported him during his sister’s suicide. A kind and loyal friend to the end, Yuka’s been with Kakeru throughout school and is (unsurprisingly) in love with him. Like the other survivors she travels with, Yuka has a mysterious power of her own called the “Hand of Glory”, which results in the ability to negate any other powers within her surroundings. Though it’s the most passive ability amongst the entire group, it certainly proves to become one of the most powerful abilities throughout the series.
