An arrogant scientist awakens in the middle of a muddy pigpen, and the last thing he remembers is eating a raw pig liver and collapsing in the subway. He quickly gathers that he has turned into a pig and is now in a strange fantasy land. As he struggles to grasp reality, a young girl named Jess comes to his aid. Jess happens to be a Yesma—a discriminated class of servants distinguished by their telepathic abilities and the silver collars around their necks. Despite his inappropriate thoughts about her, Jess makes sacrifices for his sake, and the pig resolves to repay her the best he can within the limits of his new body.

But Jess' generosity does not absolve her from the prejudice the Yesmas face daily, and the pig begins to suspect that Jess is in greater danger than she thinks. While he wants to visit the royal capital and beg the king to change him back into a human, the pig realizes that he cannot simply turn his back on his kind savior.

I like this anime for the character's charm, the simple story, and the fun and unique idea of a man being turned into a pig. The art style was good and fit with the anime. The storyline didn't have too many cheches, but I will have to say it will get dark at some moments in the anime. The characters in the anime react to situations and events in realistic and clever ways. Being a pig he needs to plan out how to get out safely without or Jesse getting hurt.

The series has some minor flaws, but if you enjoy a silly isekai, I ...

Mixed Feelings
Tonally dissonant and poorly produced, but an intriguing story with some surprisingly hard-hitting emotional high notes.

ButaLiver appears to be a typical isekai of the 2020s (this time the twist is that the protagonist is reincarnated as a pig), but rather than giving him some kind of overpowered skill that allows him to cruise along the plot with ease, the setting puts our hero in a difficult spot with very little to work with. The heroine (unfortunately) still falls back into a stereotypical mold and is way too comfortable to put up with the hero's oftentimes wildly inappropriate inner thoughts. He simply came across as crass ...

A guy is isekaied as a pig in a pigsty, saved by a nice looking slave girl who is on her way to sacrifice herself but nobody knows why and nobody forces her, he will use his poor intellectual skills to try to help her sacrifice herself but he doesnt know why she does and don't even bother knowing.

That show is the quintessence of fast food animes, one episode to try to hook you then a poor drop of the plot distilled in each episode to try to maintain your interest until the fall.
The art is basic and became worse after every episode, common to ...
