Hey guys, author here with an update on Shikai's backstory.

Shikai is a 17-year-old rich kid who defies the entire stereotype. He's living off his dead parent's inheritance in his penthouse in Osaka. He's an introvert who closes himself off from the rest of the world because of his own problems. His left eye is a Mystic eye of Enchantment. He lost his parents when he was very young to unknown murderers. He can fight (Bases his fighting style off of Luke from Street Fighter 5) but he prefers not to. He speaks in video game and anime references. He enters the Grail War on his own accord, to become a hero from the shadows like Batman, or Sasuke. He also hopes for the unlikely; making friends. But will he prevail in his quest, or will his crippling depression bring about the end of humanity?

Relationship with Servants from the Character's point of view:

Astraea: "To be honest, Astraea is the best servant I could ask for. She's the one who gives me the courage to get out of my room and do something to change this world for the better. We've become best buds and sparring partners. It's like we've been childhood friends."

Shuten-Douji: I call her my "little sis". She's always there for me when I need her the most. She needs to work on cleaning her room though. The last time I stepped in there, the whole room smelled like booze. Also, HOW CAN SHE DRINK SO MUCH!?

Kiara: I honestly have no idea why she was summoned. I'm not even into that kind of stuff, She's definitely sketchy. Her entire room reeks of aphrodisiac. She's also been looking around my room for something. I hope she doesn't find my Makima plush!
