My Superpowered Device Connects to Anime Dimensions

“Mr. Ye Shuo, could you tell us how you became the strongest person in the world, step by step?”

“I've never thought of myself as the strongest. I'm merely standing on the shoulders of another dimension.”

When enemies from beyond the stars invaded, Earth's forces were driven back at every turn, and the entire world was plunged into a disaster without precedent.

Ye Shuo, a transmigrator from another world, unexpectedly obtains the Omnitrix, the transformation watch from the animated series Ben 10. But instead of turning into all kinds of alien heroes, his Omnitrix transforms him into the anime characters he knew by heart in his previous life.

Artoria the King of Knights, Kurumi Tokisaki the most evil Spirit, Nobunaga Oda the Sixth Heavenly Demon King, Altair the Military Princess... Ye Shuo will use the powers of anime characters from his previous life to save another world.

(Note: This is not an invincible-protagonist story. The one with the ahoge won't just cut everything in half and end the story with a single swing!!!)
