Meet My Oc: Hotaru Kuromori

⸻

Basic Information

Name: Hotaru Kuromori

Age: 27

Height: 5’6”

Weight: Appears to weigh about 160 lbs due to her solid, soft muscular frame—but in reality, she weighs closer to 145 lbs. Her Quirk subtly shifts her energy signature and makes her feel “lighter” when in motion, especially in combat.

Hotaru (蛍) means “firefly,” symbolizing her glowing, electric-blue energy and the way she flickers in and out of sight during combat.

Kuromori (黒森) translates to “black forest”—a nod to her shadowy presence and quiet, intimidating look.

Quirk: PolterBlast

Type: Emitter

Description:

Hotaru’s Quirk allows her to telekinetically lift, control, and manipulate both light and heavy objects with ease—ranging from something as small as a coin to something as massive as a car. However, the true danger lies in her ability to charge those floating objects with explosive energy and detonate them at will. Whether it’s flinging debris mid-air or making an entire wall burst into a concussive blast, she controls destruction with deadly precision.

Her energy has an electric-blue glow when active, crackling around her hands, arms, and the objects she’s manipulating. The more energy she channels, the more intense the glow—and the more strain it puts on her body.

Strengths:

• Can immobilize or control enemies and objects regardless of weight

• Excellent for crowd control and combat flexibility

• Mid-air mobility through explosion-propelled jumps

• Strategic thinker—uses the battlefield itself as a weapon

• Silent operator when not actively using explosives

Weaknesses:

• Overuse causes physical and mental exhaustion, even unconsciousness

• If she doesn’t release built-up energy regularly, she becomes unstable or irritable

• Explosions must be carefully calculated—one misfire could injure allies

• Her precision lowers under emotional stress or panic

Gear:

• Fingerless Arm Guards: Designed to contain, regulate, and store her explosive energy safely. They prevent burns and energy surges, while allowing maximum dexterity.

• Shock-Absorbing Boots: Helps with landings after propulsion-based movement.

• Utility Belt: Loaded with stabilizers, energy monitors, and reinforced tools—everything she needs to recover mid-fight or safely unleash stored energy.

Appearance & Energy Signature

Hotaru is built for stealth and efficiency. Her outfit is streamlined—dark tones, tight fit, minimal flash. Her electric-blue Quirk energy pulses visibly when active, swirling around her hands and the objects she controls like ghostly fire. She has the presence of someone you wouldn’t want to irritate—quiet, intense, and unreadable.

Affiliation:

Hotaru is officially recognized as a Pro Hero working alongside Eraser Head (Shouta Aizawa). On paper, their dynamic works—both quiet, strategic, and favoring control over flash. In the field, they’re a terrifyingly effective team: one disables, the other obliterates.

But there’s something more between them—something unspoken. Whether it’s mutual trust born in battle or something deeper, Hotaru and Aizawa share a bond that goes beyond professional respect. Those who’ve seen them work together know better than to question it.

Personality:

Hotaru is quiet, detached, and often looks perpetually exhausted. Her body is constantly producing explosive energy, and if she doesn’t release some of it regularly, it affects her emotional state—leading to irritability or sudden outbursts. She doesn’t enjoy hurting others, but when it comes to protecting people she cares about, she won’t hesitate.

She’s sarcastic, blunt, and rarely shows emotion—but behind that tired gaze is a protective spirit who bears her burdens quietly. Her dry, almost apathetic demeanor masks a deep loyalty to those few she lets in.

Fun Facts:

• Her favorite time of day is just before a thunderstorm—she says the air feels “clean” then.

• Sleeps with noise-canceling headphones to prevent herself from waking up at the sound of her own energy crackles.

• She’s surprisingly good at puzzles—says they calm her down.

• Loves cats. Doesn’t it it. Aizawa knows.
