He's described as abnormal, but very easy to talk to. Sora has been known to interact with almost all of the cast, and is known for acting natural around even the 'weirdest' of characters, such as Nagisa Ran. Despite this, Sora has stated he feels like he doesn't have to try to be normal in Yumenosaki, because everyone is a bit different and everyone treats him fairly. Thus, he values happiness and appreciates his unit members for teaching him what is 'normal' to others. He aims to learn the 'magic' that Natsume Sakasaki and Tsumugi Aoba used on him that made him more appreciative of those around him and saved him from feeling alienated. He has expressed his worries that others won't like him if he reveals his 'full self' because of judgement he's received in the past. Not much of Sora's past has been revealed, but there are parts in stories that imply he's had a history of abandonment or attachment issues due to isolation because of being alienated when he was younger, similar to Leo Tsukinaga, but he did it 'intentionally'. This “strange” behavior caused him to be bullied as a kid and become a shut-in (hikikomori in Japanese), but when attending Yumenosaki, he felt much more loved and cared for, especially after joining Switch. Sora is extremely emotionally aware, but due to his unusual way of verbally communicating, he cannot communicate emotional support in an 'understandable' way, and expresses by describing colors. He gets overwhelmed in crowds because of too many colors of people being present, and usually doesn’t carry a phone due to there being so many things working inside of it that it overwhelms him.

As a result of his synesthesia, he often references the 'colors' of other people. He goes at his own pace and loves to hang out with others, but dislikes crowds due to his synesthesia (meaning he can smell, hear, and feel emotions as different colors). Sora is an energetic and extroverted boy who loves parkour and video games. He wears a pale yellow hoodie with two side pockets beneath his unbuttoned blazer. His hair is a bright yellow with lime green streaks on the right side and is tousled with his bangs long and curved upwards while the rest of his hair is of average length. Sora is a fairly short boy with a small build.
