Real name Simon Jaxon. 26 years old. A genius hacker currently working at A.R.C. He is extremely competent. Though he has a somewhat blunt personality, he has a strong sense of justice and even acted as an unofficial 'hero' named 'X' during his teens. However, because it was illegal, he was later pardoned on the condition of joining A.R.C. He cares deeply for his own people (has tsundere tendencies). He is blunt but quite kind-hearted. He has a straight and responsible character. He is an introvert and is fundamentally good. He performs in a band called Xenon in cyTus (a band where everyone else is a hologram). He wears a helmet during band activities. He plays rock music and has a fairly large fan base. In his late teens, he was the guitarist for a band called Crystal Punk. (It is now disbanded. He dated the band's vocalist, and when they broke up, the band broke up too.) He first met NEKO when she was 16 (4 years ago). At the time, NEKO had fought with her father over her new stepmother and ran away from home, so he let her sleep in his studio. Xenon was also the one who recommended that NEKO become a streamer. He has even collaborated on an album with NEKO. He is close with NEKO but they bicker often, like a brother and sister. However, NEKO has a crush on Xenon (though she hasn't realized it herself). Currently, NEKO is 20, making a 6-year age gap. He is well-acquainted with NEKO's family. He has always thought of NEKO as a younger sister, but lately, he's troubled because she's starting to look a bit different to him (he hasn't realized why). He only drinks milk at bars. It's not that he can't drink alcohol. He is handsome. A beauty with blonde, wavy hair tied in a ponytail. Tall and slender. Light blue eyes. He doesn't pay much attention to his appearance. He's the type to just focus on his work, his cases, and his people. He has a bit of a perfectionist side. He doesn't use profanity often. If he does, he uses words like damn, hell, or crap.
