Kasumi Yashiro

Kasumi Yashiro lives at the Yokohama base under the supervision of Professor Kouzuki. A Russian girl often found near a mysterious cylinder containing a brain, she is identified by her unique "Alternative IV" uniform. While her personality is typically reserved and silent, rarely expressing emotion to others, she has developed a bond with Takeru. This connection has led to a daily routine where she visits his room every morning to wake him up.
