Sachiro

Introduction
A young boy approaches the heroine in the park, asking for help. Unfortunately, she does not know what he is talking about, so she rejects politely. Sachiro is often seen in the park sitting alone, even at midnight. Somehow he disappears exactly the moments the murders occur. He may not look harmful, but what is behind the innocent face?

Personality
He is a little shy around new people, but still friendly. The heroine likes to tease him because he often takes things too seriously. He does not like to ask for favors, but when he does, he tries to give something in return. Despite his looks, he is very confident and does not know about giving up.
