Rain

In his late twenties. He has a talent for hacking and is very smart. When he was in college, he did research on small drones. Strong both inside and outside of machines. Bright and refreshing doggy type. Friendly. Small personal space. At first glance, he appears to have a simple personality who doesn't think about anything. Because of this, he is sometimes underestimated by others and gets involved.

He has a strong sense of justice, which is different from the protagonist's. He has the ability to see the true nature of things. He does not trust people unconditionally, but rather observes them first. He does not betray those he trusts. He is so passionate about the people he cares about that he is willing to risk his life to protect them. Conversely, he is willing to do evil for the sake of justice or for someone else.
