* NiceGuy

* TheStoic: Usually has a neutral expression and doesn't express his emotions or raise his voice often.
* NotSoStoic: He laughs his head off in episode 3. It's quite a sight to behold. [[spoiler:He also expresses his anguish and frustration about being unrequited by Chisaki.]]
* TheQuietOne: He reveals to Miuna that his naturally quiet and emotionally distant nature bothers him, especially since the four Shioshishio kids express themselves more freely that he does. It's implied that he believes it to be the reason why he never fully integrated into the tight circle of Hikari, Manaka, Chisaki and Kaname in middle school.
* ObliviousToLove: He doesn't seem to notice Manaka's feelings for him. [[spoiler:Or he may have noticed her affections as evidenced in episode 23 but did not believe they were done out of romantic love and it was because she was curious of the surface instead, Manaka also later confessed to him that she was in love with Hikari.]]
* SecondLove: [[spoiler:He is Chisaki's, once she learns to let go of Hikari and accept a new love.]]
* ShipTease: Has quite a bit of this with Chisaki even though their relationship is quite removed from the rest of the LoveDodecahedron drama in the series.
** [[spoiler:Until the second cour rolls around where the ShipTease is turned up and it is revealed that the two have been in love with each other all along but various circumstances kept them from getting a RelationshipUpgrade.]]
* PatientChildhoodLoveInterest: [[spoiler:With regard to Chisaki, though they were a bit older than most when the trope came into effect.]]

It is revealed that she had some feelings for Tsumugu five years ago, which developed further into love during the time they spent together. However, she is constantly in denial about it because she cannot believe that she fell in love with him within the span of five years while she knew Hikari since she was born and she is aware that Manaka likes Tsumugu as well.]]
** [[spoiler:Although it turns out later that Manaka's interest in Tsumugu was actually based on her admiration for the surface and she was really in love with Hikari.

She seems to resent Manaka on some level, too, though she tries to repress this in fear of change and the destruction of their friendship.
** She only seemed to resent Manaka when she started to try to get Hikari and Chisaki together. Even though Chisaki herself asked her to forget about it and especially as she is trying to step out so as not to trouble Hikari's pursuit of Manaka.
* UnresolvedSexualTension: [[spoiler:She has plenty of this with Tsumugu.]]

Friends with Hikari, Chisaki and Manaka. Kaname is an perceptive, easygoing boy who is Chisaki's chief confidant. He is polite, but straightforward, and seems to have a mischievous streak.
