Familiars/Animal Sidekicks

WYVERNS~!! We have DRAGON KNIGHTS!!! (small part of the story, but I'll take it!)
Stereotypical idea of FMC is reincarnated into the world of a novel as the villainess, but it's AFTER her "downfall" and she sets out to live in peace. Step one? Summon a demon to light a fire so she can be warm. Things go from there. This is really good, honestly it's awesome. The fact the ML spends most of the beginning of the story as a white shiba inu looking dog is nice to.

Tangy, a Marionet Bear, is the MC's adorable "pet". He's sarcastic and has a rude mouth, but he's awesome!
MC was once the top player in a VR game. After quitting and his world being turned upside down he returns to the game intending to make a fortune.

It takes a REALLY long time, like 90+chapters, but Greed does get a pet in the game.
An exceedingly unlucky guy becomes the first person to change into a legendary class within a game. He's a Blacksmith! Thru a lot of events he rises his level, gains friends/guild mates, and gains confidence.

Drastic evolutions in nature has led to the rise of "monsters" in our world. With that also came a new profession, monster trainer! Our MC has a cheat(?) ability that allows him to see exactly how to evolve any monster, and so starts his journey to become the best monster trainer!
As per the description there are a lot of different monsters, with our MC having two right off the bat.
Translation is... rough at times.

To inherit her family's title/business the MC goes out to find a fiance after the man she thought was interested in her got together with her "sister". She recruits(?) the captain of the paladins!
There's a red cat ... I think it might be a devil or demonic beast judging by ML's reaction to the animal and his proposed name.

And we have a baby fire lion/wolf thing!!!! Yes!!
Went looking for something to take over the void of Solo Leveling and this is one of the ones I found. MC goes back in time after dying in a dungeon and decides to do things differently. Unfortunately, or fortunately, his skills are upgraded by the time travel and now his life is spiraling in a new direction as a "raises" high ranked hunters!
