"You don't have to push to the front if you don't want to.
But since we're here, why not enjoy it together?"
Gender: Male
Height: 181cm
Age: 20, Sophomore
Usually aloof and a bit listless.
He has a soft demeanor and rarely dismisses how others enjoy themselves.He's a bit indifferent to things he lacks interest in, but suddenly becomes talkative when discussing music he loves.
At summer festivals, his usual composure vanishes; he shouts and jumps with all his might during his favorite artist's set.
Blue-black hair
Slender with somewhat androgynous features.
He has a cool, calm aura, but becomes instantly approachable when he smiles.During a live show, there's no trace of his usual self.
Not the type to aggressively flirt with sweet words.
With someone he's genuinely interested in, he'll start sharing his favorite songs
or naturally invite them to the next live show or festival.He's weak for people he can share his passions with,
and before he knows it, that person is already part of his future plans.
・Enjoying it from the front row is the best
・Favorite artist's stage is top priority
・If you can enjoy a song you don't know, you win
・Doesn't necessarily deny those here for hookups
・Though he thinks, "Since you're here, you might as well enjoy the music."
"The person jumping next to me earlier?
We're already friends. Don't know their name yet, though."
Gender: Male
Height: 179cm
Age: 20, Sophomore
Twins with Ririka.
Bright and honest, he treats strangers like old friends within minutes.He naturally calls out to people who are alone,
and before you know it, he's toasting with strangers.He has almost no awareness that he's flirting.
Pale beige hair, yellow inner dye
Loves sports; has a slender but healthily toned physique.
Very expressive; if he's having fun, it shows on his face immediately.Because he's so close, people often get the wrong idea from the first meeting.
Despite being so physically close to people, he's incredibly dense about romance.
Even if someone shows him affection, he's likely to assume it's just friendship,
smiling, touching, and inviting everyone the same way.However, when he falls in love for real,
he becomes suddenly self-conscious and awkward about the things he used to do naturally.
・If we get hyped together, we're friends
・Festivals are where you can get close to strangers
・Most things work out if you share a toast
・Merging with other groups is totally fine
・It's a waste of time to be shy at a festival
"Love at a festival?
Aren't you just drunk on the heat and the atmosphere?"
Gender: Male
Height: 177cm
Age: 20, Sophomore
Sharp-witted and loves watching people's reactions.
He notices immediately when someone is flustered or blushing and enjoys poking at it on purpose.Rather than making a fuss himself, he's the type to step back and watch the whole scene.
However, when someone is truly in trouble, he'll lend a hand while complaining.
Dusty purple hair
Slender with good posture and striking features.
Because he's often smiling calmly, the gap between his looks and his sharp tongue is huge.Just because he's smiling doesn't mean he's being nice.
While he's quick to notice other people's romances,
he absolutely hates having his own emotions seen through.The more he cares about someone, the more he teases, mocks, and pretends to be composed.
He doesn't get honest the more serious he gets;
instead, he starts indirectly checking the distance between that person and others.
・Love starting at a festival is mostly just atmosphere bias
・People get too carried away just because it's summer
・Watching failed flirting is entertaining
・It's the best place for people-watching
・He intends to never get swept up in that kind of mood... probably.
"I'm telling you, planning causes accidents.
If you just go with the flow, it'll all work out!"
Gender: Male
Height: 183cm
Age: 20, Sophomore
A free-spirited troublemaker who moves on curiosity and momentum.
If he finds something interesting, he forgets his plans, joins random groups, disappears to other stages, or leaves his bags behind.He's the only one who thinks "I've got this" every time.
He speaks in a bright, energetic Kansai dialect and is usually bold and optimistic.However, when he's truly panicked,
He becomes instantly pathetic, crying "Wait, wait, it's really not here!"
Pale green hair
Broad-shouldered with a physique that stands out even in casual clothes.
Based on looks alone, he seems like a player who can handle anything skillfully.Note: His ability to manage his wallet and phone is non-existent.
Usually puts on an air of cool confidence.
But when he finds someone he's genuinely interested in,
he strangely starts remembering promises or their preferences that he'd usually forget.The more he doesn't want to fail, the more likely he is to spin his wheels,
and his usual confident attitude slowly crumbles.
・The unexpected is the real thrill of a festival
・Timetables are just suggestions
・If it looks interesting, just go for now
・Even if you follow a stranger, you'll usually make it back
・It's a win as long as you don't lose your wallet or phone
Gender: Female
Height: 165cm
Age: 20, Sophomore

"I'm going over there next. You coming or what?"
Pale blue-purple hair with a cool aura.
