Kujibiki Tokushou: Musou Hāremu ken - Chapter 229

Crossing to One Piece world, he became Roger’s younger brother.

I am Supreme

Spread or announce my might in the world,

I am the Supreme

Medicinal material is poison if it cannot cure; a man who does not become a god will perish as ashes

………

Heavenly order has flaws, humanly world has injustice

Cast aside romance, for evils prevail

Misery brings forth kindness, rage won’t lead to disputes

Beyond principles and rules, let me carry out the execution

Spread my might in the world, slaughter injustice of the world

Blade in hand, passion in heart;

Passing judgement for life or death, sentenced by heroes with the blade,

Staring at the world with cold eyes, I have no regrets in my life

……….
