The supporting character's harem is very normal - Chapter 87 Ryne – Mom?

In a world ravaged by radiation and the remnants of war, Dylan is far from a classic hero. A lieutenant with a tainted past, he's just trying to survive the ruins of a dying world... until the day he wakes up bound and surrounded by the mutilated corpses of his comrades.Captured by monstrous creatures, he soon realizes he’s been transported to another world. A world far more dangerous, far more brutal—where only the strong survive, and even monsters are hunted. Saved in extremis by Maggie, his commanding officer, he begins a desperate escape. Their only hope may lie in their encounter with Élisa, an elf abandoned by her kin, and their discovery of a mysterious power: anima gems—stones imbued with spiritual essence that can enhance body and soul, and unlock the path to awakening.No One under 18 admitted

This crossing is so strange, death crossing, game crossing, etc. are probably barely acceptable, but why can you cross even if the fish tank is broken?

and actually passed through the magic tree in “OVERLORD” that is said to be able to destroy the world?

No! It is sad enough to regenerate into a plant. The protagonist, Ainz Ur Gong, the undead king, has also accepted the adventurer’s guild mission and wants to kill me!

I want to change my destiny! Live! I want to-surrender!

Ainz: Since he has accepted the job commission from the Adventurer’s Guild, deliberate failure is detrimental to the prestige of Ainz Ul Christine (the “surrender” button has been deducted)

actually died as soon as he crossed, but there is still a chance to return~ from the beginning of the magic tree to this world.

I must change my destiny this time! Live!

However, Kenny wasn’t ready to let go of Rory either! A fight for the omega’s heart, who’s gonna emerge the victor? And what if they decide to share instead?| - | e x c e r p t | -|“Arch for me, pup.” The dark alpha husked and more color rushed into Rory’s face as the order settled in his stomach.For the first time in his life, Rory was completely nude in front of a man. He had assumed losing his virginity was gonna be brisk, and that it was gonna happen in the dark.He never counted on it going down this way, with an alpha whose dark eyes made his weak kneed and tongue tied, whose voice made his insides clench up, and whose touch made slick gush out of him like he was a faulty faucet.He pressed his flushed face into the sandalwood smelling sheets, limbs trembling as he arched his back even more, till his ass was very high and his chest pressed into the bed as well.“There you go, that’s a good boy.” The Alpha growled out, hands reaching out to knead his hips, and when he delivered a spank on Rory’s ass, a stuttered whimper spilled past the pretty omega’s mouth, muffled in the sheets.Moments later, fingers were digging into the omega’s hair, jerking his head up just as another spank got delivered on his second cheek, and this time, there was nothing to muffle the high pitched sound and it filled the air in a melodic tune.“Don’t muffle those sweet sounds, gorgeous. I want to hear every sound you make, I need to hear you as you fall apart from pleasure in my bed tonight, and that’s exactly what’s gonna happen.”
