★Point
This is a modern dungeon romcom. In this world, only women have a “level” system, so only they can enter dungeons and power up. Men do not have levels, but they have EXP instead, and they can transfer it to women through physical contact. When that happens, the woman levels up, and at the same time, she also gets strongly stimulated.
Because the setting is different from a normal dungeon story, it feels pretty fresh. And since the main guy, Tatsuya, cannot enter dungeons himself, this is less about tense fights and more about erotic interactions.
★Characters
MC: Mura Tatsuya
Heroine: Naruse Suzuka, Matsumoto Honoka, Okumura Aina, Hamano Yura
Other: Sagara Chie, Naruse Kanako, Kobayakawa, Okumura Sana
★World setting
Dungeons appear worldwide, but only women benefit. Women gain EXP and level up, becoming stronger. Men cannot level up, instead they generate EXP and transfer it through physical contact.
The stronger the contact, the bigger the EXP transfer.
Side effect: women feel intense stimulation.
Because of that, men are seen as:
★targets for pleasure
★EXP banks
EXP resets every time they sleep.
★Main story
Tatsuya is asked about his EXP in class by Sagara-sensei. He stays silent. A classmate says he has none.
Later in the infirmary, Tatsuya shows his mark: (無) / Empty.
Sagara suspects something is wrong, since it should show “0”.
She touches him → instantly receives massive EXP → collapses from overwhelming stimulation.
Truth:
Tatsuya’s EXP = ★無量大数 (basically infinite).
Past:
He once liked Hamano Yura. He tried transferring EXP by touching her finger.
Result → she convulsed, fainted, hospitalized, and transferred schools.
Next day, Sagara locks him in infirmary and asks for EXP again.
At first he refuses, but after hearing her dream, he agrees.
Even simple contact overwhelms her again → she faints.
★Route: Naruse Suzuka
Tatsuya helps Suzuka from a rude customer.
Suzuka recognizes him and goes home with him.
After dinner, she tries to seduce him but stops after seeing his “empty” mark.
She reveals truth:
Her mother has Petrification Disease.
Cure = Soft Golden Peach from deep dungeon.
Her level is too low → she needs fast EXP.
Her mother worsens (1 month left).
Tatsuya agrees to help despite risk (transfer could be fatal).
They start with finger contact → already extreme reaction.
Suzuka moves in with him.
Daily EXP transfer → handholding → kissing → stronger contact = more EXP.
She often faints but keeps going.
Result: level 170+.
She enters dungeon for a week → gets Soft Golden Peach → saves her mother.
After that, she leaves.
Before leaving → kisses Tatsuya and promises future relationship.
★Route: Matsumoto Honoka
Honoka = kind senior + wants to be school nurse.
She fails interview due to harassment accusation.
Tatsuya suggests applying at his school → she succeeds.
Problem:
Male students obsessed with her
Female students bully her (low level)
Tatsuya helps secretly using artifact disguise.
He becomes “mysterious helper” and transfers EXP behind curtain.
Honoka reacts strongly but keeps asking for more repeatedly.
Her hidden lewd side appears.
Later, students go missing in dungeon.
Honoka wants to save them → asks for more EXP.
In infirmary, she pulls Tatsuya, hugs him → stronger EXP transfer.
Almost gets caught by teacher.
She actually knows it’s Tatsuya (bandage clue) but pretends not to.
She levels up → rescues students.
After that, she invites Tatsuya to keep coming → continues EXP transfer.
