Februar Zwei ranks among the 12 Month Demons, initially a minor antagonist allied with Dezember Zwolf to resurrect the Demon King for personal glory. Her loyalty shifts fluidly to whichever faction holds power, later joining Alba’s group against Dezember.

She manifests as a red-haired, red-eyed child despite surpassing 200 years in age, typically dressed in a blue-and-white tank top and red miniskirt. A sentient black spherical shadow with a mouth replaces her left arm, functioning as a retractable tentacle with limited range. This shadow exerts brute force capable of puncturing stone walls.

Februar Zwei adamantly identifies as a "young maiden," a delusion comically undermined by physical frailties like dislodged dentures or hip pain during movement. She ends sentences with "-hoga" and exhibits opportunistic tactics, favoring surprise assaults on distracted foes.

Her core power enables brainwashing through shadow-tentacle contact, injecting microscopic DNA particles to dominate minds. She controls up to 150 targets simultaneously, though strong-willed individuals resist. Offensively, the shadow executes piercing strikes—like her thwarted attempt to stab Janua through the chest—yet all elimination efforts fail.

Her involvement begins by transporting Janua to a dimensional void housing the first Demon Lord, Rchimedes. There, she tries brainwashing Janua, but external interference breaks her control. Later, feigning unconsciousness during Dezember’s conflict, she ambushes him by hiding her shadow within his attack, foiled preemptively.

Subsequently, she appears beside a sealed Alba, explaining his condition while attempting to brainwash him for his mana reserves. Alba resists effortlessly. When allies scatter in caves, she aids their regrouping.

"Februar Zwei" translates to "February Two" in German, denoting her place among the Month Demons.
