MTL - I Bound Aizen - Chapter 38

She was a medical expert, talented and beautiful. She was reborn as his little wife. Her in-laws did not like her, her husband did not love her, and she was as timid as a mouse. She was weak and easy to bully.

The world was once at war with 10 alternate worlds. This was known as the Concept War and our world won 60 years ago. All of this was concealed so no normal people are aware of this fact in the current time.

After the death of his grandfather, the high-school student Sayama Mikoto is suddenly summoned by the giant corporation IAI. He learns this world is headed for destruction due to the acceleration of the Minus Concepts. To prevent this, negotiations must be undertaken with the survivors of the other parallel worlds so their 10 concepts can be released.

And so Sayama is caught up in the final battle to clean up after the Concept War which left behind so much enmity.

Zavier met Cosmic Consciousness after his death. He was satisfied with every system that Cosmic Consciousness exhibited, so he wanted all of them. Surprisingly, the Cosmic Consciousness obliged him.

Zavier was reborn in an isekai full of magic and alchemy. Now, he had many routes to upgrade. Interestingly, to coordinate these systems, Cosmic Consciousness gave him the gift of being able to duplicate himself. He could clone a finite number of himself to manipulate these systems.

Magus, Alchemist, Mesmer, Tamer, Hunter, Vampire, Werewolf, Dragonknight, Necromancer.....

By the way, it wouldn't appear NTR or some bullshit harem of courtships. MC of course will have harem but not for cliches.

Giles transmigrated to a world where everyone practiced beast-taming, and he was adopted by the owner of a beast-taming arena from a young. However, Giles could only run errands and do basic chores since he didn’t have any talent for beast-taming.

One day, the arena owner had to go on a long trip, so he entrusted Giles with the management of the arena.

Faced with a bunch of baby beasts waiting to be fed, the inexperienced Giles could only tell them about the stories that he’d heard from his past life. [Pet Beast Guru Duck finished listening to “The Ugly Duckling”, evolved into an “Eight-winged Swan Beast”!] [Pet Beast Beetle Bug finished listening to “Godzilla”, evolved to learn “Ultra Heat Beam”!] [Pet Beast Lil Ape finished listening to “King Kong”, evolved into an “Invincible King Kong Beast”!] [Pet Beast Green Haired Dog finished listening to “Greek Mythology”, evolved into a “Cerberus”!] Even that rock pet beast in the corner.

After listening to Giles telling the story of “Journey to the West”, the rock split open and evolved into the Ancient God-tier pet beast, “Heavenly Sage Sun Wukong”!

When the arena owner returned, he was stunned, I told you to take care of the arena, and you trained them all to become Divine Beasts?!
