樹里

Masaya's childhood friend and the adopted daughter of Jonathan J. McCoy. She is a top-class mechanical engineer, as everyone agrees. She acts immediately when she thinks of something, and has a "go for it, even if it seems dangerous, it feels weird if you don't see it through to the end", but she is a genius whose basic principle of common sense is almost screwed up. She has a good attitude, and doesn't mind making sacrifices (for others) for the sake of her research.

To correct the tyranny of SHE, she set up her own team, and plans to make a fortune using the development data for sex toys that she inherited from a certain person. It is a mystery why she is so obsessed with SHE, and there are various rumors circulating about the matter.

She is a girl who is a little bit out of touch with common sense, but her nature and preferences are quite normal. She has a bright and easy-going personality, but she is not very good at relying on others. Also, her happiness vector is quite different, so it is difficult for ordinary people to get along with her. Her curiosity is second to none.

"If you come with me, you'll never be bored. Time will fly by and every day will be exciting."
