What if Aizen Sōsuke descended into the world of Naruto?

An Ran finds himself in the Ninja World playing the role of the mastermind Aizen. To fully unlock his character's potential, he joins the Akatsuki under the name Aizen Sõsuke. Just as he begins his infiltration, a mysterious invitation pops up:

You've been invited to the Dimensional Chat Group.

And that's when chaos begins.

Dimensional Chat Log:

The Actor: Hey guys, I'm Aizen. Just joined.

Newbie here.

Konan: Welcome! Funny timing - Obito brought in a new recruit too.

Gintoki: Wait, a new recruit? Isn't Itachi supposed to join in like... two years?

Konan: Not Itachi. He says he's Aizen Sosuke. Claims his strongest illusion is Kyōka Suigetsu. Then he pulls out a sword like he's some kind of samurai. Totally bizarre, right?

Gintoki: ???

Sawamura Spencer Eriri: ???
