[WARNING: This book contains adult content.]
    Kai was the best underground fighter alive.
    Then he slipped on a wet floor and died. Classic.
    He woke up in Aethon — a world of magic, legendary weapons, and monsters that level cities — with zero mana, zero sword skills, and one ability the System itself couldn't classify:
    [Martial Arts Mastery — UNRANKED]
    Then he killed a Rank-B beast with one punch. Live. On stream. In front of forty thousand viewers from his home world who had nothing better to do on a Tuesday.
    Now he's the most-watched streamer on two worlds, his viewer gifts are funding an ability tree no one has ever seen, and something in his combat aura is doing something it absolutely should not be doing.
    SSS-rank entities — creatures that haven't moved in centuries — are walking toward him.
    Not to fight.
    The System has no category for what they want. It just keeps sending the same alert:
    [WARNING: SSS-Rank entity has marked you as a compatible mate]
    [Current count: 1]
    [Kai: ...]
    He just wanted to punch things and hit 100,000,000k followers.
    This is not what he signed up for.
