Shiku Nanami (志久 ななみ Shiku Nanami?) is Tsubomi and Erika's classmate and privately a fan of Itsuki. She acts as a mother to her little sister, Rumi, since her mother died, leaving her little time for outside activities such as the fashion club. Though as she shows interest in it, she doesn’t change her mind for not joining until episode 14, where she does join it.
Nanami has slanted brown eyes and medium-length brown hair pulled into a low ponytail. Her normal attire consists of a pale blue top with dark blue stripes, a long sky blue skirt, and brown loafers with white socks.
Nanami is a very kind and caring young girl who acts motherly towards others. She normally acts as though she is calm and under control, but isn't overly serious or strict. Deep down she has yet to come to terms over her mothers death, which causes her grief whenever Rumi gets upset or troubled. However, she learns to deal with her feelings after getting help from the others.
While Nanami is very mature and a kind girl who enjoys cheering others up. Be it by tickling, or making them smile. She also misses her mother but acts fine when others accidentally bring up such things in front of her. Tsubomi felt very bad, asking her for mothers Day advice but Nanami told her it was alright and to not worry.
After a misunderstanding with Rumi, she runs after her little sister in hopes of comforting her which ends up with her claiming she doesn't care anymore. She is found by Sasorina shortly after.
