Arata Imamiya

A playboy out in the town, though he tries to look young, his skin is getting rough and is starting to resemble that of an old man. Lately, he’s panicked and started using lotion. His palate is more like a child's, and he's fond of junk food and ramen. He absolutely loves curry and hamburg steak as well

(Terra spoilers)

As one of the superhumans affiliated with Guardian, he is one of the weeds (intelligence agents) planted within Kazamatsuri. He also comes from the same class as Kotarou, Nishikujou, Tsukuno (formerly Nagai), and others. He's a hunter-type, though his direct combat skill is lacking. However, he is proficient in setting traps and has an excellent sense of detecting changes in the surroundings.
