Naruto: Dimensional Domination

Uchiha Linyu transmigrates into the Naruto world, where the dimensional barriers have shattered, and becomes a member of Konoha's Anbu.

The System's very first mission is to have the protagonist kill the Third Kazekage, but his surroundings are crowded with powerful figures from other dimensions, leaving him with no way to make a move.

Here, the protagonist meets Teacher Saitama from One-Punch Man, Ichigo Kurosaki from Bleach...

Mission complete! Congratulations, you have obtained a Sage Body enhanced by Conqueror's Haki.

Congratulations, you have obtained a Rasengan enhanced by One-Punch Man's power.

Congratulations, you have obtained a Mangekyo Sharingan enhanced by the Mystic Eyes of Death Perception.

Years later, Uchiha Linyu sits in the Hokage's office and proclaims to the world:

"I, Uchiha Linyu, will unite the dimensional realms!"
