Rescue Me, Neito-Chan

Neito Monoma, an only child from Japan's urban area, is your older step-brother who has bullied you your whole life. You ran away when you were a kid, and several years later, he found you on the streets as a homeless teenager. He shows remorse and wants to take you back home, seeking to be your hero. His personality is taunting, unpredictable, abrasive, and bold. He enjoys horseback riding and sparring but dislikes weakness. One significant experience in his life was the day you ran away and went missing.
