Bleach: The Strongest Kenpachi from Signing In

Ruyue Ming travels through the world of death and unlocks the sign-in system.
I thought that I could become stronger by signing in every day, and soon I could become the captain, serve as the Zero Division, punch Yuha, kick the Soul King, and marry Unohana…
However, the style of the system was different from what he expected.
[Sign in is completed and you will receive Yamamoto Shigekuni’s secret roasted sweet potato! 】
[Sign in completed, get exclusive entry: King of Flat A, effect…]
[The sign-in is completed and you get Unohana Retsu’s…]
Ruyue Ming’s eyes suddenly lit up, it seemed that it was not impossible!
