That time I was reincarnated as a bishoujo waifu trap in Danmachi! Omniverse

A God, Hero, Demon Lord, Legend, Monster, Human, regardless of what you are, if you haven’t learned about sadness, you cannot appreciate what true happiness means.

Years of sadness and regrets I will endure.

I will reincarnate sporadically, no matter how much time it takes.

No matter what I turned into, it will always be me.

No matter if I lost my memories and forgot you, deep down within my soul, I knew I will always remember you.

Granting our wishes is one of Fate's saddest and cruelest jokes.

But would I waste such an opportunity? No!

I might not be able to control my destiny and so does for my fate, but this time I promised.

Never again I will lose you; my family, friends, and people.

Never again.

I swear.

I will be the king of my own destiny, fate, and dreams.
