Sweetheart Turned Romance Virgin Slayer

A classmate who flipped Shun’s world upside down after offering to take his “romance virginity.”

Witnessed Shun’s love flags implode time and again, although they’d never talked. While she always played it cool, however, his lonely gaze struck a chord with her...

When she caught wind of Shun’s yearning for romance, she decided to take matters into her own hands.

“I’m gonna take all of your firsts. Your romance virginity is mine!”

Hinano Kasama

Voice: Musubi Aono

Persistently Possessive Childhood Friend

Shun’s classmate and constant companion since day one. Despite their shared history, romantic feelings never surfaced between them—until now.

It turns out her aloof demeanor was a carefully crafted facade, hiding a deeper desire to transition from friend to something more.

“It’s been so long! Such a long, long time since I fell in love with you!”

Ayane Anekawa

Voice: Ayaka Igasaki

Doting & Dominant Big Sister

A friend of Mio who’s like an older sibling to Shun, sharing a stronger bond with him than he has with his actual sister.

Like Hinano, she knows the ins and outs of his flag-crush curse, biding her time while dropping not-so-subtle hints from her advantageous position as a “family member.”

“Go ahead, I’m your big sis! You can come to me for anything...”

Matsuri Hinomiya

Voice: Kosuzu Fuyumine

All-Round Nice Girl & Oblivious Female Friend

Shun’s classmate and among his closest friends. Academically gifted, she’s also the student council vice president.

Has a hidden nurturing side, supporting Shun whenever his Flag Crush Syndrome acts up. Pure of heart and intentions, she’s oblivious to anything remotely sexual...

“Oh, silly! What are friends for?”

Nayuta Uzuki

Voice: Nanami Mizuno

“Luckiest Girl” Flag Crush Buffer

Another close friend and the student council president. Seemingly immune to Shun’s Flag Crush Syndrome, she’s one of the few girls out there able to interact with him normally.

In fact, as the campus’s “luckiest girl,” she effortlessly dodges all flag-crushing chaos without even breaking a sweat...

“You’ve been served a bad lot in life, sure.”

Mio Okunaga

Voice: Kasumi Okudera

Actual Big Sister & Eroge Maker Extraordinaire

Shun’s sister, who’s playing mom while their parents are overseas on business. She mainly handles Shun’s finances, while Ayane manages his day-to-day life.

Runs an eroge company and is always pulling game ideas from his messed-up life, jokingly calling his experiences a “real hentai situation.”

“I’m a honking brother-lover myself.”

Nanaka Anekawa

Voice: Narumi Aisaka

Juicy Devoted Milf Mom

With a motherly warmth that even outdoes Shun’s actual mom, she’s made the Anekawa household feel like his second home.

She’s been aware of her daughter Ayane’s crush on Shun for a while and has been subtly playing matchmaker.

“What about if you called me Mommy?”

Shinnosuke Kasama

Voice: You Yotuba

Siscon-Obsessed Big Brother

Hinano’s overly devoted brother who always puts his little sister first. Often works behind the scenes to give Hinano an edge in Shun’s love life.

He’s got a soft spot for Shun, treating him like a younger sibling. Shun sees him as like family, too, and they share a solid bond.

“I think you’ll choose Hinano, of course.”

Shun Okunaga

Ultimate Flag Crusher

The protagonist. Whenever Shun catches feelings for the opposite sex, a romance flag is triggered only to be crushed moments later—a phenomenon dubbed Flag Crush Syndrome by his sister, Mio. As a result, he actively avoids all potential romantic interactions.
