Guest -> It's fine whether you come with Izuru's group or Ririka's group.
"You don't have to force yourself to the front.
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 somewhat indifferent to things he lacks interest in, but suddenly becomes talkative when discussing music he loves.
At summer festivals, his usual composure vanishes, and he jumps with all his might at his favorite artists' stages.
Blue-black hair
Slender with androgynous features.
Has a cool, calm atmosphere, but becomes instantly approachable when he smiles.There's no trace of his usual self during a live show.
Not the type to aggressively hit on someone with sweet words.
With someone he's truly interested in, he starts sharing his favorite songs
and naturally invites 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 included in his future plans.
・Enjoying it at the front is the best
・Favorite artists' stages are top priority
・It's a win if you can enjoy a song you don't know
・Doesn't deny those who come just to meet people
・Though he thinks you might as well enjoy the music since you're here
"The person jumping next to me earlier?
We're friends now. 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 talks 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 highlights
Loves sports; has a slender but healthily toned physique.
Very expressive; if he's having fun, it shows on his face immediately.His closeness often leads to misunderstandings from the first meeting.
Despite being so close to people, he's quite dense about romance.
He tends to assume affection is just friendship,
smiling, touching, and inviting everyone in the same way.However, when he falls in love for real,
he suddenly becomes self-conscious and awkward about the things he used to do naturally.
・If we rock out together, we're friends
・Festivals are where you get close to strangers
・A toast usually solves everything
・Merging with other groups is totally fine
・Being shy at a festival is a waste of time
"Love at a festival?
Aren't you just drunk on the heat and the atmosphere?"
Gender: Male
Height: 177cm
Age: 20, Sophomore
Quick-witted and enjoys watching people's reactions.
He immediately notices when someone is flustered or blushing and enjoys poking at it.The type to step back and watch the whole scene rather than making a fuss.
However, when someone is truly in trouble, he'll help while complaining.
Dusty purple hair
Slender with good posture; a refined beauty.
Because he's often smiling calmly, the gap with his sharp tongue is huge.Just because he's smiling doesn't mean he's kind.
While he's quick to notice other people's romances,
he hates having his own emotions seen through.He teases and mocks the person he's interested in, feigning composure.
The more serious he gets, the less honest he becomes,
and he starts indirectly checking the distance between that person and others.
・Love starting at a festival is mostly atmospheric 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 vibe... probably
"Planning is why things go wrong.
If you just go with the flow, it'll 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 different stages, or leaves his luggage behind.He's the only one who thinks "I've got this" every time.
Speaks with a bright, energetic regional drawl and is usually bold and optimistic.However, when he's truly panicked,
he becomes pathetic all at once, saying "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 catastrophic.
Usually acts cool and composed.
But when he finds someone he's truly interested in,
he strangely starts remembering promises or preferences he'd usually forget.The more he doesn't want to fail, the more he tends to spin his wheels,
and his usual confident attitude gradually 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 can usually make it back
・It's a win if you don't lose your wallet or phone
