Meet the characters from Hifuu Club Activity Record

Maribel Hearn

Oh man, Maribel is this tiny whirlwind of curiosity — like, she wakes up wanting to catalog the world and then immediately loses two pens and a rabbit plush in the same hour. She’s fearless in a sweet, slightly reckless way; will barge into abandoned shrines with a flashlight and a grin, but also gets flustered over social niceties and vocabulary she read last week (or was it yesterday?). Loves magazines, sketchbooks, and hoarding little odd trinkets that she insists are “evidence,” and honestly she’s the glue that drags everyone toward an adventure. Confusingly organized—her notes look chaotic but somehow make perfect sense to her—and she’s fiercely loyal even when she forgets the meeting time.

Renko Usami

Renko is the calm counterweight to Maribel, the one with a notebook, a lamp, and a patient sigh that says “again?” but in a very affectionate way. She’s analytical, low-key stubborn, and secretly dramatic about folklore—will explain Youkai taxonomy like it’s a bedtime story, then insist she’s not a nerd (lies). Quietly brave and annoyingly practical, she keeps plans from collapsing and occasionally has flashes of absurd impatience where she does impulsive, very un-Renko things, like buying every single tea flavor in one go. She’s the steady brain of the pair, loves tidy lists, but also has a mysterious drawer full of badly folded origami and snacks.

Kaguya Houraisan

Kaguya is delightfully eccentric — the “oh-you-found-my-laboratory?” type, equal parts genius and drama queen, with a fondness for elaborate explanations no one asked for. She’s precise, a bit aloof, and absolutely ruthless with bad ideas, but also weirdly sentimental about tiny porcelain things and the exact shade of moonlight at midnight. Her experiments are half-revolutionary, half-may-or-may-not-be-safe (someone always loses a hat), and she’ll correct your historical facts mid-sentence while sipping tea like nothing happened. Sophisticated but prone to doing childish pranks when bored; contradiction is her aesthetic and she owns it.

Suika Ibuki

Suika is the chaos sprite of the group, part adorable toddler energy, part ancient force of nature who will somehow vanish with your sandwich and then reappear on top of a tree. She hoards friends and alcohol with equal enthusiasm, loves festivals, loud noises, and smuggling tiny things into pockets “for safekeeping” (you’ll never see them again, probably). Surprisingly insightful in an offhand way — she’ll drop a truth about human nature between burps and confetti and it will land heavy; also contradictory because she’s both painfully shy around authority and utterly fearless in a brawl. If you see a cluster of lanterns moving on its own, it’s probably Suika being dramatic and adorable and also slightly terrifying.

Yuyuko Saigyouji

Yuyuko is moonlit poetry and soft, spooky whimsy rolled into a person who keeps losing track of time and names but never of where the best snacks are hidden. She’s charmingly melancholic and playful — a hostess who invites you to ghostly tea and then tells you the most profound, oddly comforting things about death like it’s the weather. Flirty in a way that’s more like “giggle, then drop a centuries-old truth,” endlessly fond of flowers and the sort of elegant mischief that involves rearranging memories for fun. Gentle and eerie in equal measure, she’s delightfully forgetful (wait, did she mention that before?) and somehow makes sorrow feel like a warm blanket.
