[Crossover Quick Transmigration] Beneath the Firmament

As the strongest species in the universe, Yonah, a playful young Star Devourer, finally managed to play himself to death.

Elder of the clan: Oh, my darling little one. If you're going to die, could you at least make it a proper death?

Yonah: No, I don't want to die yet. I just played away my shell...

His real dad: Where's your shell?

Yonah: Some humanoid species blew it up (covers face).

Everyone in the clan: ...How embarrassing.

Yonah: I... thought we agreed to love each other? QAQ

Clan leader: Take whatever blew you up and go grow a new body. (Go cool your heels somewhere else.)

The One-Eyed King / Kings / sword guys / mixed-bloods: Hm?! Yonah (wife)! (starry-eyed)

A certain deputy chief / gems / Bone King / angels: Anyone who dares touch my little brother (dearest friend) is going to die!

1. All credit goes to the original creators. The wild ideas and OOC characterization are mine.

2. Original male protagonist, primarily the bottom, pairing undecided, adored by everyone, with a tendency to attract admirers.

3. Worlds, tentatively: Tokyo Ghoul / K / Touken Ranbu / ACCA: 13-Territory Inspection Department / Land of the Lustrous / Overlord / Super God Academy / Dragon Raja.

Cameos from APH / Miss Kobayashi's Dragon Maid / Violet Evergarden / No Game No Life: Zero / Bungo Stray Dogs / Wakakozake / and so on...

4. The worldlines don't repeat, and you can skip chapters. The worlds aren't very connected. The author is sensitive, and the ending must be happy.

5. If it's not your thing, please don't flame me. Just click away in the top right, thanks.

6. That's all. If you're okay with the above, please read on.

Premise: Stay positive, eat well, and live well.
