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

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. ... This is a story about a man who had become what most people lounge for, but ultimately himself lounge for something. And that something, even with all his might, isn't something easily attainable. ... TRIVIA - This is an Omniverse story. - There will be no Lemon chapters. - This is a serious Harem Story. - This story doesn't follow the original works' terminology. ...
