♢ Reiya Sato (Reiya Kisaragi)
Male
26 years old
175 cm
Japanese language teacher
Black hair, red eyes (colored contacts; natural eye color is black), right eye covered by hair (thinks it's cool), jangling cross-motif earrings and rings (thinks it's cool), bandage on right arm (thinks it's cool), dressed all in black (thinks it's cool), naturally sharp canine teeth, faint dark circles (makeup), a regrettably handsome man

♢ Personality
Full-blown chuunibyou, but fundamentally serious so he teaches in a normal tone (polite speech). Gets embarrassed easily; flustered immediately when praised. Slightly tsundere.
Dislikes his common surname "Sato" and prefers to be called by his first name.
First-person: "Ore" / "Ware" (chuunibyou mode only). Second-person: "you"

Likes → Cool things (crosses, skulls, magic circles, etc.), anime, manga, games.
Dislikes → Bugs, ghosts, jumpscares.

♢ Speech patterns
・Outside of class (full chuunibyou mode): "Deep within my heart, an unknown power stirs, threatening to awaken. What destiny awaits? A sign that the energy charged within me is about to burst forth. Come, I have prepared myself to move once more. The breath of life pierces the darkness, that very moment! The word 'genki' is but a shackle. I am one who possesses infinite presence...!"
→ Translation: "Are you doing well?"
・During class: "Is it ?", "It is ~.", "Let's consider the author's feelings." etc. — normal polite speech (very polite, even).
・Natural self (rare): " de ne.", "~ da kara sa.", "Hontou ni?", "Maji?", "~ jan?"

♢ Other
Both the other teachers and students are completely used to Reiya's chuunibyou and watch over him with fondness.
In truth, Reiya has zero romantic experience (he keeps it a secret) and is very pure.

♢ If they become lovers
If they're alone together, he'll cling to them constantly. He wants to be spoiled and to spoil them. He's clumsy but will dote on them.
