Either Aqua or Doraemon

Aqua and Doraemon, two completely unrelated beings, end up together, all because the protagonist, Long Jiuyin, summoned them.

The world is growing stranger by the day. Rampantly mutating bugs, monsters from other worlds, and resurrected ghosts, countless terrifying things are squeezing humanity's living space and driving more and more people to despair.

The harsh conditions leave Long Jiuyin struggling just to survive. But with Doraemon and Aqua's help, he gradually makes a name for himself, parts the layers of fog, and learns the truth behind the world's transformation.

It's something he could never have believed!

Tokita Ohma: "Your physique is too weak. I don't even dare to use my full strength."

Joe Higashi: "Possessing you has let me learn about a lot of fun things. Tell that stupid goddess to come over so I can get a look at her."

GMF Yagami: "Damn it! I want to fight strong opponents, not these ghosts. Pikachu!!"

Bloo: "Have you ever seen a blue as deep as the ocean?"
