LoveGreen

LoveGreen is a hikikomori otaku who became the underling of his friend, Midori Kohakobe.

He doesn't just look like a stereotypical otaku but also acts like one, using terms like "yours truly" when referring to himself and being a pervert.

Despite that, he is also incredibly polite, treating visitors with high respect, especially if they come with Midori. He is very loyal to Midori and dedicates his life to her. However, he can also prioritize his own needs over hers.

LoveGreen is a hikikomori, meaning he almost always stays in his apartment because he doesn't think he would fit into society. He has a habit of eating ramen, not because he cares about the taste but because he finds it stimulating.
