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.

If you're jealous of a pig, you become worse than a pig.

Living thus far, I never imagined being the envy of a pig. What are the chances of finding someone so kind and heartwarming that she is willing to fully understand and accept you? Indeed, we live in a cruel world where mutual differences and the unwillingness to understand separate us. Thus, finding the one that is willing to reside by you is such a lucky and precious thing I could have ever expected.

Just like the sentence: "Though most people tend to glance at the tall sunflowers in full blossom, however, there will still be ...

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 ...
