Green

Green serves as a school staff member at Eden Academy and is a veteran of the East State Navy. Despite the imposing impression his facial scars may give, he is genuinely warm-hearted and sincere, earning him deep affection from the students. In the second season, entrusted by Henry Henderson, he leads Damian and his friends on an outdoor camping trip, guiding the children with his wealth of wilderness survival experience and life wisdom — a trusted elder figure whom the students regard as both mentor and friend.
