Multiverse: Path of the Harem Against Fate

My name is Ryu. I trained in martial arts my whole life and became a professional to control my own destiny with my strength. I didn't want to be controlled by anyone, so I trained as hard as possible. But in the end... I still got killed... at least I managed to save my girlfriend. So, I thought it would all end at that moment. However, at the end of my life, I awakened an unknown artifact. From that moment on, my world turned upside down. I just didn't imagine as much as this artifact would give so much power, and It also was going against the gods of the multiverses and destiny itself. First world: To-love-ru ----------------- -Disclaimer- 1) The protagonist's harem will not betray him. Understood! That goes for all your possible girls. And it will be a huge harem. 2) This novel will be about wish fulfillment and will have many clichés. Any woman the protagonist has sexual relations with will be an adult. 3) My first and second language is not English. I'm doing a translation on top of my writing, so there will be grammar issues, but I'm trying my best. Thanks in advance for your time. 4) Images are not mine; they belong to the artist. If the creator wants me to remove it, just let me know. 5) This is just fanfic. Please know that I do not claim ownership or credit for the original characters; the author has full rights over them. 6) And finally, I'm a newbie, and this is my first novel. Good luck!
