Issue 1

"Nagatoro-san and Senpai" (長瀞さんと先輩) is the first issue of the Nagatoro-san webcomic.

Summary
Hayase Nagatoro met with her senpai Hachioji under a gazebo in the park to thank him for supporting her during a sport competition the previous day, saying she spotted him easily on the crowd because of how shady he looked, making fun of him for being always so uncomfortable in public place and then showing him the medal she won, exposing some cleavage while explaining she wasn't wearing a bra that day. As the boy got agitated she mocked him for believing she was going to show him her boobs, telling him she wouldn't show them to a "creep" like him.

So she asked him what he wanted to talk to her about since he was the one who invited her, scolding him for not looking at her in the eyes and mumbling instead of talking clearly, calling him "creepy" and saying that it would have been hilarious if what he was about to said was a declaration of love.

Then Nagatoro asked her senpai if he wanted to know what she really thought about him, saying that if she had to describe him in a word it would be "gross". Thus explaining it was gross how he walked, how he was unable to look at the people he was talking to, how he always sought for other's approval and have no sense of independence, how sometimes he sulk like a child, how his hair looked like a bird's nest and how his physique was so tall and bony. She then asked if he knew that the girls at school called him the "Beansprout Prince", where the term "prince" only referred to his last name.

As the boy began crying, Nagatoro explained that he was like a worm to her and that she only likes to play around with him; she also informed him that she was pretty popular with boys and was confessed by several people. including the handsome president of the school council, however Nagatoro has always turned them down as she was not interested. The girl then said that a creepy otaku with no friends like Hachioji couldn't confess to her as it would mean that he didn't know his place.

Calling him a "maggot" Nagatoro took her senpai's arm in order to prevent him from running away, then she kept insulting him for how pitiful his face was and how pathetic he was for crying in front of a younger girl, telling him that it would be better if he simply died. As she called him "embarrassing", "maggot", "human garbage", a "pig" and a "cockroach", finally Hachioji confessed his love to her and asked her out.

Nagatoro was shocked and called him an idiot for saying something like that to her after what she said, then she accepted to have a date with him, telling him that she was doing it only to make him her own toy to play with and that she would have made fun in breaking him. Nagatoro then gave the boy her favorite handkerchief to wipe off his tears, telling him not to bother in giving it back to her after it was covered in his tears, sweat, drool and mucus since it would be simply "too gross".

Characters

 * Hayase Nagatoro
 * Hachioji (unseen; POV)

Trivia

 * When Nagatoro speaks about the sport competition she won, she's very vague, also her medal was drawn with too few details to identify what the sport to which it's associated; however it could very well be judo just like in the manga, where the protagonist took part to many sport club but only judo at a competitive level.
 * In stark contrast with the manga, Hachioji didn't meet Nagatoro in this first issue but it's implied they knew each other for a while, also he asked her out shortly after the story began and they were shown as an odd couple for the rest of the webcomic.
 * Albeit unseen, as he acted as a POV, Hachioji is called by name since this very issue, while in the manga he is mostly unnamed and called with various nicknames by the other characters; though eventually his surname was revealed in Chapter 82.
