Crossover: I Declare Myself the Strongest

The four strongest people are Saitama, Kusuo Saiki, Shigeo Kageyama, and Satoru Gojo.

The consciousnesses of their four worlds beg them to go play somewhere else. Their worlds have already been wrecked by them, and can't take having these four living Buddhas around anymore.

So the four who've been kicked out of their rooms team up to wreak havoc on other worlds.

The conquest of the world begins! (Not really.)

More accurately, it's the Anime World Rescue Plan. (Not that, either.)

To be precise, it's... a vacation outside their own worlds. (Right.)

Satoru Gojo changes into casual clothes (at a price nobody else could imagine), puts on a pair of sunglasses, pats Mob on the head, and says, "Well, from now on, I'm your master! Aren't you happy?"

Mob looks at the hand on his shoulder and thinks silently. After spending so many days together, he feels that rather than Mr. Gojo taking care of him, the other two are taking care of Mr. Gojo. This man is so different from how he looks...

Saiki silently agrees. But Kageyama, you have no right to say that. You two are equally troublesome.

Saitama, the strongest in the truest sense of the word, stares at Satoru Gojo with round eyes that somehow seem mocking. "Mob and I have the same author, so in a way, Mob should be my junior disciple (son). Now, let me ask you: are you sure you want to be Mob's master?"

"..."

[Advance warning]

- This really is just a laid-back slice-of-life story.

- There won't be any fight scenes. (If they start fighting, will anyone need to save the world? It'll already be destroyed worldwide...)

- OOC: yes

- Daily updates: no

- Note added on January 4, 2021

- I've lost the motivation, so I'm putting this on pause for now while I think about what happens next.
