Ultraman: I’m Hyper Zetton, and I Want to Taste the Mysterious Four Ultras

Good news: I've transmigrated to the Ultraman world, and the light of bonds is beckoning to me. Bad news: Wake up and stop dreaming. As Hyper Zetton, there's no way you can become an Ultraman. Instead, the cosmic drifter Dyna, the advanced fusion material Cosmos, and the series' chosen one Zero are on their way, weapons in hand. Xia Chao: “I hereby report someone for cheating!” “Huh? I'm the one cheating? Then never mind.” [Monster protagonist, non-human + invincible, no angst + no female lead]
