Sera is calm and light-hearted, but can sometimes be chaotic. In contrast to her adorable appearance and voice, her sense of humor is rather peculiar, much like her fellow ex-NIJISANJI KR member So Nagi; while she claims to be "seiso," she has a tendency of swearing in frustration or shouting very loud when playing video games, and occasionally becoming menhera when the situation doesn't turn as she intended.
Sera can also be described as a "NIJISANJI fangirl-turned-Liver," in that she gives a lot of supports towards her fellow NIJISANJI Livers; for example, when Hyakumantenbara Salome debuted, Sera was quickly influenced by Salome's speech pattern; she gradually got emotional so that she became in tears as she talks with Mayuzumi Kai and Miyu Ottavia during their respective call-in streams before their retirements; and she jokingly asking if Levi Elipha cares about her or not during the latter's birthday stream. She also watches other NIJISANJI Livers' streams quite often, and can sometimes be seen on their chat.
Outside of her fellow ex-KR branch Livers, Sera particularly gets along well with ex-NIJISANJI ID Livers, especially who also speak Japanese, considering ZEA Cornelia her girlfriend and talking with Nara Haramaung very friendly; in Spring 2022, partially due to the merger of NIJISANJI KR into the main branch, her collaborations with the main branch Livers has significantly been increased, often interacting with the Livers like Sakura Ritsuki, Belmond Banderas, Gwelu Os Gar, Nagao Kei, Sorahoshi Kirame, Seraph Dazzlegarden and so on.
