Background / History

Exusiai was a Penguin Logistics employee assigned to the Texas squad when she came under questioning by the Lungmen Guard Department. She and her team had transported a refrigerated container that should have held fruit, only to find the injured and amnesiac Mizuki inside; the team brought him to the hospital. 1 2

Her first kiss with Mizuki happened accidentally after he awoke. The incident left the normally uninhibited Exusiai conspicuously shy and led to an escalating dispute with Croissant, who was made to compensate her with pay cuts and Guardian Guns. 2 3 As Mizuki joined Penguin Logistics, Exusiai became increasingly open about wanting to be near him and hired Lee's Detective Agency to investigate his missing past rather than conceal her concerns from him. 3 7

Exusiai and Mizuki gradually furnished a shared room, went shopping together, and began taking mutual initiative in their relationship. Their relationship was confirmed after they spent the night together and discussed their feelings. 10 11 12 13 She remained devoted to him despite the arrival of several people connected to his past, including Skadi, Laurentina, and Muelsyse. 21 25 41

After moving with Penguin Logistics to Rhodes Island, Exusiai continued to stand by Mizuki through revelations about the Seaborn, the Sea of Life, and his increasingly unstable condition. She learned that the Sankta descended from Sarkaz and later accepted that her connection to Mizuki had begun to change her as well. 67 114 154 164

Exusiai and Mizuki received their marriage certificate in Laterano; she regarded his companionship as more valuable than the certificate itself. 163 165 Even as Mizuki became capable of spreading his consciousness across Terra, Exusiai remained concerned with giving him a sense of home and belonging. 160 170

Appearance

Exusiai is a short Sankta woman, standing under 160 centimeters, with red hair and a luminous halo. Her cheerful appearance and bright presence are repeatedly likened to a little sun. 56 67

• Red hair, which Mizuki compares to roses. 12
• A halo that can illuminate dark rooms and visibly reflects her emotional state. 9 70
• Wings capable of concealing a firearm. 67
• Often wears a Penguin Logistics-style outfit; she had a matching uniform tailored for Mizuki. 10
• Later favors more feminine clothing, including a black gauze nightgown. 127

Personality

Exusiai is bright, energetic, impulsive, and unusually willing to break rules. Her colleagues describe her as sunny, lively, and difficult to intimidate, though this reputation has also made potential partners wary of approaching her. 7 10 She is playful and teasing around Mizuki, but his attention can make her unexpectedly bashful and hesitant. 2 10

She is fiercely protective of those she loves. When Mizuki and Texas disappeared after the Cat Gang attack, Exusiai personally tore through multiple hideouts, interrogating gang members with frightening precision and demanding to know where her “husband” was. 16 She also refuses to hide her attachment to Mizuki, proudly displaying their relationship before her sisters and friends. 41

Beneath her sociable exterior, Exusiai is selective about whom she truly lets close. Mizuki recognizes that while she appears warm toward everyone, very few people reach her heart. 184 Her commitment to him persists through jealousy, competing relationships, revelations about his nature, and fears over his mental state. 87 154 160
