Anime Crossover: Awakening the All-Purpose Rinnegan from the Start

W-Wait, isn't this the Rinnegan?

"Congratulations, Host, you've awakened the All-Powerful Rinnegan. The Otsutsuki System is now active."

A voice sounds in my mind. The Otsutsuki System?

What does the Otsutsuki System mean?

"Host, you currently have a human body. The Otsutsuki System will help you evolve into a member of the Otsutsuki Clan."

"The world you've arrived in is facing a crisis of destruction. Only after you become a member of the Otsutsuki Clan will you be able to save this planet completely."

"Don't worry, Host! You won't be fighting alone. You have companions here."

"Companions? What do you mean? Are there other people with an Otsutsuki System?"

In this all-anime world, there are people like you who came from the original world to the anime world, and they also have Systems like me.
