The supporting character's harem is very normal - Chapter 501: Meeting Arine again

Yo, Hi! I’m Frank, I made a deal with a demon to pay me some money for receiving a guest for a few days every week.
I had no idea about what I have done.
On May 1st, Conan ‘the God of Death’ came to my house. I was forced to let him in and we get involved in a criminal case.
On May 8th, Bruce Wayne ‘Batman’ came to me. I was forced to follow him to fight crime.
On May 16th, Hannibal Lecter, The Silence of the Lambs, came to my home. I can only say that I really can’t stand my guests.

Attention: This is not a furry story!____________________________________An unfortunate guy found himself stranded inside a forest with a questionable system that turned his gender upside down. He will have to scavenge and survive in this hostile place, meeting many enemies and few friends. He will have to navigate a Cultivation Society that either hates (Kills) or wants to 'contract' Beasts.Will he find his place in this world or will he become someone's pet? Will his system help him Evolve into Divine Beasts? Or will he change into a Human to explore this world?____________________________________I'm new to this kind of thing, so any advice or criticism would be welcome. (Especially grammar, I can get most words right, but I can't hear where to put ',' or how to separate sentences nicely.) I have searched the web for any image that could properly portray our protagonist while keeping it free. I have found a very nice picture that was close to what I was going for, but it IS AI-generated and I have no idea how copyright works. I do not own that image, I have simply searched for a free picture describing her features and found this... if you are the owner of this picture, please write me a message and I will take it down as soon as possible. (The Image is temporary and I will commission an artist later for a more accurate depiction~)

A young middle school student faces a life-altering choice. Destined for mediocrity and without a War Spiritual Bloodline, he dreams of transcending his ordinary existence and becoming a high-status War Spiritualist. His world is transformed when he becomes bound to the “”Godly Pet Evolution System,”” enabling him to activate his War Spiritual Bloodline and cultivate divine pets, even from the most unlikely sources.Armed with this system, he defies expectations by nurturing underdog spirits into formidable allies. The seemingly weak flower spirit evolves under his care, as does his Lord White Dragon, challenging the mightiest thunder-attribute battle spirits. Even when presented with a Diamond Demonic Spirit Card, he counters with three Epic-Demon Spirit Cards of his own.His journey takes an unexpected turn as powerful entities, including the Six-Tailed Demon Fox, the Phoenix Holy Maiden, and the Queen of the Seas, vie to become his second battle spirit. Faced with a wealth of choices, he refuses to settle for just one and ambitiously aims to harness them all.

June 15 of the year 2010, the third awakening happened. Several smaller worlds had returned to connect with the main world as living beings of different races started to appear and some people managed to connect with the origin and gain control of various powers: control of fire, of water, of wind, of air, and of earth... In the midst of all these confusions, towers that gave unimaginable powers began to appear in all corners of the world, where those who already had powers could upgrade and become more powerful or even those who did not have powers could receive powers through tests of the tower. And because of these towers, conflicts started to happen in all corners of the world by those wanting to monopolize these towers.

Luan Dimas was betrayed by one of the people he trusted most. However, in his final moments before being killed, he was transported back to four months before the third awakening that started the apocalypse on earth. Being a man who lived for a thousand years and had accumulated several techniques, he now had a new chance to correct some of his early mistakes. Luan decided to make the most of this new chance that the heavens had given to him.
