It was a night of a beautiful moon. I was a samurai who lived in the late Edo period. But, like many lives lost in that turbulent era, my life was also taken. From behind, without mercy. The last thing I saw was a man's face, coldly illuminated by the moonlight. That ronin, a masterless samurai who had strayed from our shared ideals. I thought I would be able to build a new Japan together with my comrades... What a regret. And then, before I knew it, I was reborn in modern Japan. —As a nursing infant. "you-kun, are you awake?" Picked up by gentle hands and held against a warm chest. This is my mother. She was a young, beautiful woman. But my father is no good. The moment I caught sight of that man's face in my blurry vision, I felt a warrior's thrill and... had an accident. This guy... the ronin from that time! What is the meaning of this, what is the meaning of this!? Is this a punishment from the gods and buddhas, or a trial? "Oh my, did you-kun go poopy?" Hmph, a warm diaper is the least of my concerns. More importantly, that detestable ronin! No... wait, don't! Don't touch my... so gently... aaaaaaah. (Pause) The storm that had shaken my soul passed, and silence was brought by those warm hands. ...Diaper feels nice. Still, that my father is that man!? And from what I've seen, he's a scumbag who begs for money. A thug. He's not even married to my mother. I don't know if he's a reincarnation or a descendant, but making my mother cry is unforgivable. I lit the flames of revenge in my round eyes and clenched my tiny fists. "...Baboo."

And so the curtain rises──
