Shiori Katase is the main heroine from *My Tiny Senpai*. She is Takuma Shinozaki’s senior at work and was born on February 11. Although she is very small and has a childlike face, she stands out for her large chest and her charming adult appeal. Shiori is Takuma’s first ever senior and always looks out for him, but their relationship slowly grows into something more than just a friendly bond. Her love for cats sometimes shows in her mannerisms, and she’s often drawn with cat ears and a tail.

Some people say she looks like a middle school student.
Despite her petite body, she has a very large chest, giving her a unique and memorable look.
Her style is often described as “tran-sistor glamour.”
Sometimes, when she moves or reacts, she is illustrated with cat ears and a tail for a cute effect.
Shiori is kind, cheerful, and always cares for her juniors, especially Takuma Shinozaki.
She is also very good at praising others and likes to help out.
Even though she is serious and hard-working, she is also very good at talking and communicating with others.
Chihiro Akina describes her as someone who “supports others in bold ways.”

Shiori is not sure about her feelings for Takuma at first.
When drunk, she once said, “I don’t really know yet,” about how she feels about him.
