One Piece: I Am the Digital Emperor

After transmigrating to the world of One Piece, he awakens the Digital Army System. He can get good things through special sign-ins, and exchange all sorts of things for Digital Points. Following the System's requirements, he can use those points to trade for Digimon.

Watch as the protagonist builds an army of Digimon to take on the entire world of One Piece.

The Marines, huh? How about the Bagra Army and the Steel Empire?

The Four Emperors, the Fifth Emperor, huh? How about the Bancho Five, the Four Holy Beasts, and the Dark Masters?

The Holy Knights, huh? How about the Royal Knights and the Twelve Olympians?

The Shichibukai, huh? How about the Seven Great Demon Lords?

Imu, huh? Take a taste of this punch, combining the power of every Digimon!

Anyway, if anyone else has a problem, step forward. Either you cling to life by a thread, or you die in agony.

Everyone: “…?????!!!!!”
