Suneko

The president of the student council, she's thoughtful and has a strong sense of justice. She's very well liked, but is also somewhat of a lecher. Suneko is also very knowledgeable about computers, and is a VTuber in secret. She once had a trepanation, a procedure in which a hole was drilled in her skull.
