I'm looking for monster training novels in the style of Monster Pet Evolution or where the mc captures the monsters and manages to transform or use the powers of the monsters (if there is a novel in this style). No harem. Sorry for the errors, I used the google translator. Thank you.
Don't remember well, but i think that these two are maybe what you want. Charm Of Soul Pets Monster Paradise
Super God Gene- is something like this but normally rather than pets you get some parts of their feature like wings , sword etc. Pets are also available but are difficult to evolve and rear. But MC has many pets.
The idea is soo good but the silly harem and nonsensical glorification of the mc ruined the whole thing.
