San (Alpaca)

San is a recurring character in Beastars. He is Louis' friend and was a cellmate to him and Kyuu when he was raised as a livestock and locked up with other herbivore children in the black market.

Appearance
San is a light colored Alpaca with fluffy fur and large eyes. Just like Louis and Kyuu, he has his livestock brand imprinted in his left foot. He wears a tracksuit just like Kyuu.

Personality
As soon as he and Kyuu recognized Louis, their long lost cell mate, he is quick to apologize for hurting Legoshi and is rather easygoing and upbeat, the complete opposite of the cold and calculating Kyuu. When in action though, he is very observant of his enemies and can quickly pinpoint their physical weaknesses.

Skills

 * Finding Physical Weaknesses: San has the ability to quickly scan an enemy‘s body to discover all of their weak points. He works with Kyuu due to her outstanding skills in knife fighting.

Kyuu
Kyuu is a long time friend of San's. She and San were both friends of Louis while sharing the same cell during their time as raised livestock. After Louis was adopted by Ogma, Kyuu and San have since found ways to survive the black market together, and have presumably been friends and companions ever since. Between the two, San is quite friendly, while Kyuu is more standoffish.

Louis
Once San realized Louis was Number 4, he lets his guard down and is very friendly and apologetic towards him and Legoshi. He seems to be grateful to meet his old cellmate buddy in contrast to Kyuu who seemed distrusting, especially with Legoshi.
