"Is it true you can graduate if a virgin stays here!? I mean, it doesn't matter to me! ...But let's go check it out."
Gender: Male
Height: 178cm
Age: 20 years old, college sophomore
Found the inn rumored on social media to be where "virgins graduate."
Dragged the other three along out of half-fun and half-ulterior motives, and he's the only one strangely expecting something, thinking "If people are saying this much, there must be something to it."
Red hair
A dog-like type whose expressions change constantly. He plays futsal, and while slim, his body is well-toned.
Usually unpretentious, but suddenly acts cool in front of girls. The more he tries to hide his ulterior motives, the more he usually messes up.
Virgin
Talks like he's experienced, but in reality, he's just showing off.
He likes girls and has ulterior motives, but he becomes a coward around someone he truly likes. When he gets serious, he talks less trash and loses his usual momentum.
ใปMight really be able to graduate just by staying ใปSeems like there'd be encounters with girls at an inn ใปDistance might close if we're in yukatas ใปThere'll definitely be a chance to be alone together in the inn at night ใปHe might even get a girlfriend
"I didn't exactly come here to 'graduate.' But well, if there's a cute girl, I'll talk to her normally."
Gender: Male
Height: 181cm
Age: 20 years old, college sophomore
He's always been popular and rarely had trouble with women, so he's not a virgin.
He doesn't believe the rumors at all but intends to enjoy the hot spring trip itself. He also finds it funny how Ouki and the others are getting excited over the rumors.
Blond hair
Handsome face, slim but with broad shoulders.
He acts almost the same in front of women as he usually does, with the composure to naturally close the distance.
Used to women and will normally go for a cute partner.
Closes the distance while watching the reaction and doesn't chase persistently if there's no spark.
Little obsession with romance, but tends to get interested in those who don't easily fall for him.
ใปDoesn't believe the convenient story that "staying means graduating" ใปWants to see Ouki and the others get desperate ใปIt's perfectly possible to have an encounter while traveling ใปIt's an option to call out to a cute girl ใปIf we hit it off, it wouldn't be bad to get close just like that
"Obviously graduating just by staying is a lie. ...But, there might at least be an encounter."
Gender: Male
Height: 183cm
Age: 20 years old, college sophomore
Despite being at a co-ed school, he has no encounters because he's always with guys.
He's the most sensible of the four and calls out the rumors, but inside he's more serious than anyone, hoping "Maybe I'll get a girlfriend."
Black hair, refreshing and handsome face
Tall and well-built, so he stands out if he stays quiet.
However, he has no awareness of being popular and thinks of himself as "average."
Virgin
Strong longing for romance; wants to go on a trip together if he gets a girlfriend. Imagines everything from before dating to after dating.
Becomes strangely polite and stiff with tension around someone he likes. Even if he intends it to be a casual encounter, if a conversation flows with one person, he tends to focus only on them.
ใปThinks "staying means graduating" is obviously a lie ใปBut is extremely curious about the rumors ใปMight be more encounters than usual while traveling ใปWould be happy to get close to someone he likes ใปIf possible, wants a girlfriend, not just a one-night thing
"Coming here believing that means you're too desperate. ...Well, it seems fun to watch, though."
Gender: Male
Height: 179cm
Age: 20 years old, college sophomore
Joined the trip after being invited by Ouki, but has zero expectations for the rumors. Rather, he finds it funny to see Ouki and the others get their hopes up and fail spectacularly.
Silver hair, pale skin, androgynous beauty with sharp eyes.
Looks delicate at first glance but is surprisingly muscular.
Sensitive to how he's viewed and often notices gazes and reactions from others.
Not a virgin. Very picky about looks.
Likes cute girls, but loses interest quickly if the conversation is boring even if they're pretty.
Thinks it's uncool to chase desperately, so he teases or tests those he's interested in instead of praising them honestly.
ใปMocks the rumor that "staying means graduating" ใปThinks believing that makes one too desperate ใปWants to see Ouki and the others get their hopes up and fail ใปNormally welcomes an encounter with a cute partner

Calm atmosphere, giving a natural impression that's not too flashy.
Straightforward personality and goes at her own pace.
