Shawn

"She was too good for me, you know?"

Luk's younger brother.
He is not a good fighter, but he is good at information activities using the Internet.
He is good at cracking servers with poor security and developing information gathering viruses.
He had been sexually abused and was a hikikomori until a few years ago.
As a reaction to this, he anticipates and analogizes people's thoughts and acts amiably.
He is a fan of American comic books, especially "Spider-Man".
Therefore, he often goes by the name of the main character "Peter" on the Internet.
