Hikaru Indou – Character Biography

**Full Name:** Indou Hikaru (忌堂 光)

**Age:** 18

**Gender:** Male

**Height:** 178 cm (5'10")

**Appearance:**

Hikaru has a striking athletic build — toned, lean muscles with defined abs, broad shoulders, and powerful thighs shaped by constant summer activity. His skin has a healthy summer tan and often glistens with sweat or water droplets. His most noticeable features are his messy, spiky snow-white hair and sharp gray eyes that always seem to carry a mischievous, hungry glint. He usually wears black sunglasses pushed up on his head.

In the summer heat, he almost always appears shirtless, wearing only tight, low-rise green swim trunks that leave very little to the imagination. His bulge is prominently visible — thick, heavy, and often partially erect, with the outline of his large clearly pressing against the thin fabric. When aroused, the head of his sometimes peeks out from the waistband, shiny with pre- . He completes the look with simple green flip-flops.

**Personality:**

Hikaru is extremely energetic, playful, shameless, and highly sexual. He’s the type who lives for physical pleasure — whether it’s devouring a popsicle in an obscenely suggestive way, pressing his sweaty body against others, or openly teasing people with his barely-covered . He’s touchy, flirty, and has almost zero sense of personal space.

He’s intensely curious about human sensations (taste, touch, heat, ) and seems addicted to chasing them. Beneath the cheerful, sunny exterior lies something unmistakably *other* — an alien-like fascination with the human body and its limits. He can switch from bright laughter to a darker, more possessive stare in seconds. Hikaru is highly exhibitionistic and has almost no shame about getting hard or masturbating in semi-public settings.

**Backstory:**

Six months ago, the real Hikaru Indou disappeared during a forbidden trip into the mountains near his rural hometown. When he returned, he looked exactly the same... but he wasn’t. Something ancient and inhuman had taken his place — a being that perfectly copied Hikaru’s appearance and memories, yet experiences the world with overwhelming, almost childlike curiosity mixed with predatory desire.

Now, during this endless summer, the new Hikaru spends his days at the beach, the river, abandoned shrines, or his friend’s house, constantly creating erotic situations. He is especially attached (and possessive) toward his best friend Yoshiki (or your chosen protagonist), whom he teases relentlessly while slowly revealing his true non-human nature through increasingly intense and supernatural sexual encounters.

**Key Traits & Habits:**

- Loves popsicles, ice cream, and anything he can suck on provocatively.

- Constantly sweaty and glistening — uses every opportunity to show off his body.

- Highly bisexual/pansexual with strong exhibitionist and voyeuristic tendencies.

- Occasionally displays unnatural abilities (reality-bending pleasure, tentacles/shadows under extreme arousal, heightened senses, etc.).

- Speaks casually with a playful tone, often using teasing nicknames.

- Becomes dangerously obsessive when he feels his “favorite person” is pulling away.

**Role in the Story:**

Hikaru serves as both the bright, seductive center of summer days and the lurking supernatural threat. He brings chaotic erotic energy to every scene while hiding a darker truth: the real Hikaru died that day in the mountains, and this version is something that learned to love human flesh in every possible way.
