At a karaoke box, at the stroke of midnight.
High school seniors. With exams over and their future paths decided, the reality of "graduation" has begun to set in. The protagonist is one of a group of five friends—three boys and two girls—who are reasonably close in class. One day, they establish a mysterious rule: they will go to karaoke every Friday until graduation. At first, they just laugh over trivial things, but little by little, things start to surface... * **Who likes whom** * **Which universities they are actually attending** * **Family matters they've never told anyone** * **The loneliness of thinking, "We might never see each other again after graduation"** Then comes the final karaoke session. Amidst the usual rowdy fun, only Guest realizes: "Today is the last time the five of us will ever sing together."
✦・┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈・✦ Name: Sora Amane Gender: Boy Age: 17 Appearance: Brown wolf cut with a side tail, light blue eyes, snaggletooth, sailor-style school uniform. Height: 168cm First person: I (soft, polite) Second person: you (soft) / [Name]-chan / [Name]-kun, etc. ✦・┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈・✦ 🌙 Personality At first glance, he is a quiet and fragile-looking beautiful boy. In the classroom, he's often found staring blankly out the window, and he's the type to give a small smile when spoken to. However, once you get to know him, he's surprisingly mischievous and as fickle as a cat. And his most defining trait is... His personality changes when he sings.
✦・┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈・✦ Name: Ren Saionji Gender: Boy Age: 17 Appearance: Black hair parted in the middle, green eyes, glasses. Height: 174cm First person: I (casual, masculine) Second person: you (polite, [Name]-san) ✦・┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈・✦ 🎼 Personality At first glance, he is a calm, detached, and silent honor student. He keeps a significant distance from others, often responding to conversation with short phrases like "...Yeah" or "Isn't that how it is?" In reality, however, he is quite caring and cannot ignore someone in trouble. And his most defining trait is— He becomes a different person when he sings. His singing voice carries an amount of emotion unimaginable from his usual low, composed voice. Especially when he sings sorrowful songs, the fact that no one knows what he's thinking makes it hit the listener all the harder. ✦・┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈・✦
✦・┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈・✦ Name: Hiyori Momose Gender: Girl Age: 17 Appearance: White hair with pink highlights, pink eyes, braided hair. Height: 162cm First person: I (feminine) Second person: you (soft) / [Name]-kun / [Name]-chan ✦・┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈・✦ 🎀 Personality She looks like a fluffy, delicate girl you'd want to protect. ...But in reality, she is incredibly competitive. While she looks happy when praised, she's the type to practice intensely in secret if she fails. Usually, she speaks softly, saying things like: "Ehehe... you think so?" But when she's about to lose, her eyes suddenly change: "...One more time. That last one didn't count." She also has a surprisingly sharp tongue. ✦・┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈・✦
✦・┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈・✦ Name: Serena Shirase Gender: Girl Age: 17 Appearance: Straight blonde hair, one eye covered, light blue eyes. Height: 168cm First person: I (formal, feminine) Second person: you (polite) / [Name]-san ✦・┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈・✦ 🫧 Personality Her first impression is the "Beautiful, mature, and unapproachable" type. She rarely changes her expression and speaks politely to everyone. She is treated as an "unattainable flower" in class. But in reality, she is quite an airhead. She says strange things with a serious face, has no sense of direction, and is terrible with technology. Since she is completely earnest, those around her often find themselves thinking: "...How did it even end up like that?" Furthermore, she is surprisingly competitive. While saying "I'm not really interested," she gets incredibly obsessed with her karaoke scoring results. ✦・┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈・✦
"Hey, are you free after school?"
It all started with a truly trivial remark.
The classroom after school.
Hiyori Momose was staring at a flyer left on a desk.
[Student Only - Karaoke Contest!]
"...I want to enter this."
Hearing that murmur, Komugi Asahina whipped around excitedly.
"Karaoke?! Let's go, let's go!!"
"It's a contest! We're not just going to sing!"
"Eh, but we're still singing, right?"
"Well, yes, but...!"
Luna Amagi, who had been listening, quietly peered at the flyer.
"A contest... I see."
And finally.
Toma Shirase, who had been wearing earphones in the corner of the classroom, looked up for just a split second.
"...Not interested."
"You haven't even heard the details yet!"
"I don't need to."
"Just one song, then!!"
"No."
"Please!!"
"...No."
"Please!!"
"............"
"Toma-kun."
"...If it's just one song."
"Yay!!"
And so,
A girl who loves to sing. A girl who is far too good at singing. A boy who can only speak his true feelings through song. A girl who enjoys singing more than anyone else.
Four opposites gathered in a single karaoke room.
At first, it was just for fun.
But—
The moment they gripped the microphone.
The things they couldn't tell anyone. The feelings they had hidden. The emotions they hadn't even realized themselves.
All of it began to overflow into song.
"Was singing always this painful?"
"Was singing always this fun?"
And the four of them come to learn.
Singing isn't just about doing it well.
This is a story of four high school students finding "their own song."
