Fourteen-year-old Hatsune avails her Level 4 metamorphosis as a member of The Hound Special Esper Team alongside of her partner Akira. Much to Akira's chagrined frustration, Hatsune demonstrates the proclivity to behave her default lupine alternate manifestation which is only at its greatest efficacy when she is hungry—hungry as in 'have not eaten for days' ravenous rather than merely being peckish. Unfortunately, Hatsune's voracious appetite does have the tendency to displace the mission at hand. Even as this flaw is somewhat diminished as Minamoto trains her, Hatsune still has to overcome the fact that she computes and conducts in lupine/canine maneuvering rather than anthropoid action. Even with her canine conduct and gluttony set aside for the moment, Hatsune demonstrates a proclivity to become enthralled with anyone that sees past her exterior to interact with her as a human being and twice tries to claim Minamoto for herself. As Kaoru emphatically and vigorously demonstrates at her natural potency designation during an exercise regarding Minamoto and his affiliation, whoever is decided upon to supervise Hatsune will have to establish and maintain dominance right from the start without being cruel or despotic.
