[Pokemon + Pokemon + Travel Across All Regions + Beating Up Gou Hao + Multiple Female Leads + Hisui]
After Luo Chen witnessed Ash win the Masters Tournament and learned that the anime would change protagonists next season, he desperately wanted to go to the Pokemon world. Not for any other reason, but to witness Ash's adventures firsthand and beat up Gou Hao while he was at it.
By a twist of fate, he really did transmigrate to the Pokemon world and awaken a transmigration System, which let him travel between multiple Pokemon worlds.
In the Hisui world, Luo Chen: Ursaluna, here I come! Goodra, I've been waiting for you! Beni, so adorable! Akari, my wife!
In the Origin world, Luo Chen: Green, someone has come to keep you company! You're not the only one to retire right after becoming Champion. I beat Red and sent him here to keep you company!
Red: …
Many years later, after Luo Chen used his transmigration System to become the world's number one Pokémon Master:
Cynthia: I got together with him after we researched Hisuian Pokémon together.
Red: … Let's battle!
Steven: My friend, would you like to join me in exploring the mysteries of stones?
Leon: Luo Chen is just too strong. There's no hope of beating him!
Ash: Luo Chen, even though I can't beat you, I won't give up!
Doduo: How can a Hisuian Goodra be this cool? Luo Chen, I'll pay any price, so please, you have to send me one.
Luo Chen: Doduo, you're a Flying-type Champion. Why do you want a Dragon-type Pokémon?
Doduo: I have a younger sister.
Luo Chen: !
Iris: ???
The blurb doesn't do it justice. Read the story.
I think giving myself a five-star review isn't too much of a stretch 🤭
