With Kotori Minami
- She can't say "no" to Kotori whenever she pleads her gently.
- In the ED song of the first season, she is shown to look shyly at Kotori who applauds her for her archery skill.
- Placed her hands on Kotori's shoulders once µ's received a submission note.
- She has a duet with Kotori called Anemone heart.
- As a child, Honoka convinced Kotori and Umi to climb a tree with her. Scared and sitting on a branch, she held hands with Kotori and cried.
- Embarrassed when it comes to confessions and relationships.
- She got embarrassed when speaking to Eli about how to respond to the love letters she kept getting from her underclassmen.
- She also got really embarrassed when Eli expressed curiosity about what would happen if the two of them were to be in a relationship. Umi later imagines her as a possible girlfriend as well.
- She becomes flustered when Maki tells her there would be no problems if they decided to get together.
- Blushed timidly while Eli was taking a picture of her in a maid outfit next to her sister, Alisa Ayase, who exchanged romantic looks with her afterwards and clung to her arm.
- She has a duet with Eli called Storm in Lover.
- She becomes camera shy, at least when filmed by the other members.
- Couldn't bear being filmed by Rin for an interview, refusing insistently with a blush.
- Immediately moves to cover the lens when Nozomi starts filming her when she helps out at the maid café Kotori works at, also wearing the maid uniform.
- Heavily blushed and tried to cover her chest as Nozomi filmed her while she was in a bikini, both standing in the ocean.
- Despite always being against "shameless" actions, she actually has a pretty lewd mindset, coming up with the most perverted imaginations that usually involve the other girls.
- As Nozomi points out, Umi once overimagined a skit Nozomi and Rin did to tease her, having a nosebleed and fainting despite the dialog being not that lewd.
- Startled when Honoka placed her hands on her thighs when Kotori showed them the first costume design, which had a short skirt that would show her thighs.
