## Personality

No. 15 firstly appeared as an innocuous kaiju, calmly scouting its surrounding without attacking or even engaging humans. However, when attacking, the kaiju reveals its true nature as a cruel and cunning creature, not above taunting its victims.

The kaiju was very interested in Kikoru Shinomiya. Even while facing her, No. 15 stayed in its Kikoru-like form and taunted her during the entire fight, calling her "Little Kikoru." Through its powers, No. 15 gave a demonstration of its sadistic nature by digging into Kikoru's subconscious and forcing her to relive her childhood trauma.

Kaiju No. 15 also resembled Kikoru in personality, being quite eccentric and arrogant. Possibly inheriting Kikoru's trauma, No. 15 had a desperate need to gain the approval of its father-figure Kaiju No. 9, in the same way Kikoru strove for her father's praise. No. 9's cold and distant personality, however, motivated Kaiju No. 15 to become more powerful through training, only enough to gain its affection, with killing Kikoru proving to be the ultimate challenge to achieve that. Kaiju No. 15's despair upon realizing it was just No. 9's pawn and that its love will never be reciprocated, caused a deep pain in its heart, desperately begging for its progenitor's affection even as it died.

## Plot

### The Compatible User Arc

At some point, this kaiju was created by Kaiju No. 9, after the latter had killed Isao Shinomiya. Ever since being created, No. 15 seeked No. 9's love and affection like a human daughter would from her father. However, its emotions were used by No. 9 to manipulate No. 15 into getting stronger for the former's goal, being oblivious to affection and seeing its spawn as nothing but a pawn.

Kaiju No. 15 then appeared in Shibuya Ward, Tokyo, at the scramble intersection of the Hachiko exit gate. There, it proceeded to observe its surroundings for three minutes and then leave.

### Cataclysms Arc

Three month later, the kaiju disguised itself as a human before attacking some bystanders in Kabukicho, Shinjuku.

### The Second Wave Arc

During the No. 9 induced cataclysms attacks, Kaiju No. 15 appeared in the National Diet area to face off against First Division Officer Kikoru Shinomiya. Right after being recognized as a Numbered Kaiju and being given its **Kaiju No. 15** codename, the latter quickly unleashed an attacks that eliminated the officers who were aiding Kikoru, much to her shock. As it morphed back to its human form, No. 15 mocked Kikoru, who then got ready to neutralize it. Mocking Kikoru who announced No. 15's neutralization, the kaiju quickly attack her with multiple powerful blows, overwhelming her in strength and speed, eventually breaching through her Numbers Weapon's shield. Stating that Kikoru's axe isn't enough to kill it, Kaiju No. 15 then morphed its left arm into a giant axe to eliminate Kikoru. However, Kikoru evaded the attack at the last and, while following her mother's ghost through the suit, she eventually managed to hit No. 15 once in the face, although slightly. Eventually, Kikoru managed to reach her maximum Combat Power and expose No. 15's core, only for the kaiju to release a psychogenic attack on her opponent. Inside Kikoru's subconscious, Kaiju No. 15 questioned her on her reason to become stronger, only to make her reveal that all she ever wanted was her parents' praise. Upon this revelation, No. 15 taunted her saying that her parents were dead and she couldn't be praised by them ever again, with Kikoru falling in despair. No. 15 later sensed the appearance of Kaiju No. 8, much to its surprise. Sensing its immense power after he defeated Kaiju No. 13, No. 15 acknowledged No. 8's superior power and proposed reuniting with its fellow kaiju to take him down, before noting Kikoru getting back up As Kikoru found her resolve in proving to be a worthy Defense Force officer, No. 15 found itself pummeled by the young soldier, who eventually delivered a fatal blow. In its last moments of life, No. 15 showed her psyche and memories to Kikoru, revealing how much it wanted to gain Kaiju No. 9's approval only for the latter to see it as a simple pawn. Despairing, Kaiju No. 15 was then killed by Kikoru.
