Bakuhatsu Penguin serves as a strategic Messenger within Kaede Sakura’s White Kämpfer faction, coordinating group efforts rather than individual alliances. Tasked with advancing Kaede’s agenda, it orchestrates covert manipulations to sway Natsuru Senō’s allegiance, prioritizing collective goals over personal bonds.

The penguin wields hypnosis through a pendulum-like coin technique, directly overriding free will—exemplified by its control over Mikoto Kondō, whom it compels to execute Kaede’s commands. Though it denies embodying tsundere tropes, its interactions blend biting sarcasm with covert aid, prompting peers to liken its demeanor to media portrayals of the archetype.

Collaborating with White Kämpfer operatives Sayaka Nakao, Hitomi Minagawa, Rika Ueda, and Ryōka Yamakawa, Bakuhatsu Penguin leverages their trust to escalate factional rivalries. Its calculated interventions intensify clashes between Kaede and the Red and Blue Kämpfer, driving narrative conflicts in *Kämpfer für die Liebe*.

Within this storyline, the penguin isolates Natsuru by destabilizing alliances, enabling Kaede to probe his loyalties through psychological and physical trials. Its schemes peak during a decisive battle, though retreat follows when outcomes falter. The character exits without elaboration on origins or future motives, its role defined solely by these orchestrated crises.
