Don’t Toy with me, Miss Nagatoro

A lame otaku Senpai is doing his homework in the library. A group of unkempt girls takes a peek and notices that he is drawing a manga. They think Senpai is an idiot, except for one girl who takes a liking to him and starts to approach him. Her name is Nagatoro. Senpai tenses up. Who would have thought that she has an unusual kink...

Like the prey who is about to have his blood drained by a vampire, Senpai is forced to play a game of nipple-poking and continues to be teased by Nagatoro. To get peace of mind, Senpai visits a family restaurant alone. He finds Nagatoro there with other men and observes in silence. Nagatoro shows a never-before-seen side of hers.

Senpai and Nagotor encounter a storm. Since the rain refuses to dissipate, Senpai has to seek refuge in Nagatoro's house. They are left alone... Senpai is forced to have a meal with Nagatoro's friends, Gamo and Yoshi. When she sees how her friends tease Senpai, Nagatoro becomes mad.

Senpai is having lunch alone in the activity room. Someone enters the room. It's not Nagatoro but Gamo and Yoshi. Senpai is confused and Gamo forces Senpai to touch her breast... Nagatoro volunteers to be Senpai's drawing subject. Senpai feels his heart race faster as Nagatoro poses seductively. And then, Nagatoro adds, you'll be rewarded if you draw me nicely...

Looking at Senpai's long hair, Nagatoro wants to trim his hair. Senpai agrees to let Nagatoro help him nervously, only to have Nagatoro's phone ring suddenly. Things are not going as planned. The summer holiday is tomorrow. Nagatoro and Senpai line up before a famous shaved ice dessert shop. Senpai notices Nagatoro sweating profusely under the heat. He does something unexpected.

When Senpai wakes up, he's already in a wonderland. He is chosen as the world's savior, heading to the Demon King's castle with Toro Cat that he chances upon. During the summer holiday, Senpai lazes in his house with the air-conditioning. Nagatoro invites Senpai to the beach. Senpai whines as he meets up with Nagatoro. So even Nagatoro's friends are tagging along...

Today is the summer festival. Senpai is waiting for Nagatoro's invitation, but she does not contact Senpai. He heads to the summer festival, hoping to run into her. However, he meets... Senpai and Nagatoro are watching the fireworks together. As they watch by their private spot, the atmosphere around them turns awkward. To regain control, Senpai forces Nagatoro to kiss him.

The mid-term exam is around the corner but Senpai prefers to play video games and ignores his study. And so, Nagatoro starts saying, Senpai, if you fail your grade... Back home, Nagatoro plays Rock, Paper, Scissors with Senpai. Senpai lost. Instead of carrying bags, he has to carry Nagatoro now...

Does Senpai have any urges? Did Senpai hide adult magazines in the activity room? Nagatoro has a bet with her friends. Sakura is troubled by a pervert stalker. She asks Senpai to pretend to be her boyfriend. The jealous Nagatoro follows them with her friends. She sees Sakura and Senpai getting closer and closer...

Nagatoro notices Senpai run one lap slower than his classmates. The next day, Nagatoro, in a rather provocative sports attire, decides to train with Senpai. The school anniversary is near. Nagatoro volunteers to be Senpai's model. As she teases and cheers for Senpai, someone appears.

A duel between Senpai and Bucho, the outcome of which decides the survival of the art club. Nagatoro and others cheer for the timid Senpai, but they are surprised by Bucho's masterpiece. To lift Senpai's spirit, Nagotoro volunteers to be his model. Senpai isn't very happy with his work. Having had enough, Nagatoro storms out of the art room.

For the art exhibition during the school anniversary, Senpai continues to work on his piece, which features Nagatoro. Nagatoro and others go to scout Bucho's art piece but are dumbfounded by its marvelousness. Since a direct attack won't work, an ambush will have to! On the other hand, Bucho also encounters a problem. The school anniversary will begin soon.
