I Have the Barrier Fruit, So Is It Really Too Much to Use Susanoo?

He transmigrates into the age of the great pirate voyages, becomes Zoro's older brother, awakens a sign-in System, and obtains the Barrier-Barrier Fruit.

Signing in every day expands the area his barriers can cover.

Signing in every month unlocks a new way to use his barriers.

Signing in every year awakens new powers. Opening a Susanoo or summoning a Gundam isn't asking too much, right?

Garp: "Boy, how much longer are you going to keep lazing around? You're the only one who can stop Whitebeard's quakes!"

Sengoku: "You don't want to be an admiral? Are you aiming to be Fleet Admiral instead? How about this: capture Kaido and Big Mom, and I'll hand the position over to you."

Suotian: "Who cares about that? Isn't it better to lounge around as a lazy Marine with the four beauties of the pirate world at my side, and nobody daring to mess with me?"
