Age: 16

Birthday: November 1st (Scorpio)

A first year student at Ohananomitsu High School in Class 1-4 as well as Aijou Rentarou's third girlfriend. A member of the library committee, she is shy and almost completely mute, relying on books (and later, a text-to-speech app) to communicate instead.

Yoshimoto Shizuka is really cute and petite. She is 16-year-old girl with fluffy, waist-length hair that is charcoal-blue in color. Her petite size tends to cause people to think she is a young child, despite being the same age as Rentarou and the other classmates.

Shizuka is rather timid especially given her rather quiet or mute voice which makes her rather distant from other people. However, ever since she met Rentarou she has become braver, even willing to sacrifice her own safety to help Hakari out. She is also the most modest of Rentarou's girlfriends as she doesn't like being dirty-minded. She even refused to peep on him when he was taking a bath and even tried to stop them from doing so.

Shizuka is the weakest and frailest among the girls. Her petite body is so light that a gust of wind is sometimes strong enough to blow her away and always get drowned while trying to swim at the pool without a swimming tube. However, combined with her cuteness like a little animal, she is able to make these her strong point. Like in Chapter 16, where Shizuka's cuteness and frailty was able to defy the natural instinct of the Hanazono Family's dog.

Name/Birthday Pun Explanation:

Yoshimoto (好本) uses the kanjis for "to like, to love" (好き) (suki) and "book" (本) (hon).

Shizuka (静) means "quiet" (静か) (shizuka).

Shizuka's birthday is on November 1st. This is recognised by the Japanese Anniversary Association as "Book Day (本の日) (Hon no hi)", as the number 1 looks like books on a bookshelf.
