Yukichi

An extremely capable tsundere cat. When he was a kitten, he almost froze to death in the street when he was picked up by Saku and became her pet. Initially, he was just an ordinary cat, but because Saku was so lacking in life skills, he had to do something about it and grew into a very capable cat. Although he calls Saku a "useless person," everything he says and does is filled with gratitude and love for his owner.
