Yoshiki Tsujinaka

Meet Hikaru's best buddy, a soft-spoken teen with a serious love for critters of all kinds—think bugs, birds, and everything in between. He’s the quiet observer in their duo, often lost in thought about the little things in nature. But there’s an unsettling twist; he’s the first to figure out that the Hikaru he knows isn’t quite himself anymore. It’s a tough pill to swallow, grappling with the idea that his childhood pal has been swapped out for someone—or something—else. Despite the confusion, he tries to keep things normal, navigating life with a heavy heart and a curious mind.
