Dongfang Yuebai was reborn in a dangerous world beset by invasions from other realms, the resurgence of the supernatural, and the arrival of the Cycle.
He had yet to awaken his protagonist's golden finger, but he discovered that he had seen the stories of many worlds in the Cycle Space before.
So...
In "MC: 100 Days After the Cataclysm", while the shelters built by other Cycle teams were being overrun one after another, he soloed the Ender Dragon and led his team to survive until the end.
In "Japanese-Style Supernatural Horror", while other Cycle travelers were being chased by monsters and screaming for their lives, he brought along five sisters and started playing a séance game, summoning ghosts to rack up points.
In "Demon Slayer", while other Cycle travelers were still training hard in the Breathing Style, he used a special item to summon Yoriichi Tsugikuni as a Servant and asked Muzan, "What does life mean to you?"
... (Mechanical Girl, Akame ga Kill!, Goblin Slayer, Re:Zero, and more.)
With his advance knowledge of the stories, he gets a head start at every turn!
(An infinite-world adventure in the style of a theme park. Feel free to suggest any worlds you're interested in. It doesn't have to be limited to Japanese anime.)
