Episode 8/Season 2

"Why Don't You Try Bulking Up a Little, Paisen?" (パイセンさ　ちょーっと体鍛えてみねぇ？) is the eighth episode of the second season of the Ijiranaide, Nagatoro-san anime series and the twentieth episode overall.

Plot
Due to the art club's shelves being full of paintings, Nagatoro suggested to Senpai to try sell some of them at an auction, however the boy replied that no one would have payed for a student painting. At first, Nagatoro agreed, however after she found one of the President's nude self-painting she pointed out that would sell easily.

Later on, while drawing a still life, struggling to find inspiration, Senpai, after a moment of embarrassment, asked Nagatoro to be his model. At first the girl pretended to be busy in order to be prayed to, but in the end she accepted and asked him what pose he wanted her to take, leading him to tell her to assume the one in which she felt "more natural". Hearing so, Nagatoro assumed a series of stance from muay thai, boxing, capoeira and a fourth one that she assumed without thinking but seemingly made her uncomfortable. After seeing the latter, Senpai deemed it as the one on which she was "more natural" and asked her to pose in that stance, which the girl eventually accept blushing a little. While the painting was being done, Senpai and Nagatoro exchanged several glances, the first asking himself what kind of stance was that while the latter staring at him with sweetness. After finishing it, Senpai asked Nagatoro about the stance, leading the embarrassed girl to choke him in a submission move stating it was her own personal martial art style in a clear attempt not to answer him. Right in that moment Yoshi, Sakura and Gamo-chan entered the room and, while the first two simply told playfully Senpai to surrender in order to get freed from Nagatoro's move, seeing the painting Gamo-chan got quite emotional, saying heartwarmingly to Nagatoro that "it has been a while since the last time" and asking with evident nostalgia if she wanted to give it another try. Senpai asked what they were talking about, but Nagatoro stormed out of the room saying she won't tell him. Her friends running right after her.

Later that day, while having judo class in gym, Senpai performed poorly and is friendly teased by Takao. Hino and Nagatoro, who was observing him from a window in the corridor. After the lesson, the gym teacher gave flyers about the school's judo tournament to all of his students. When he tried to ask the girl if she was interested in it, Senpai noticed she had disappeared. That afternoon, Gamo-chan and Yoshi stormed into the art club room to ask Nagatoro if she wanted to join the tournament but Senpai informed them that the girl hadn't come that day, prompting Gamo-chan to sadly say that "she still feels like that about judo,” to which Senpai asked her more about it. Pleased at the boy's interest, Gamo-chan gave him a flyer of GAMOU Fighting Gym, which she explained as being her family business, telling him to give it a try; looking at the flyer closely Senpai is stunned to notice a picture of Nagatoro on it, promoting the newcomer course.

After having been told by Gamo-chan to visit her family gym that Saturday, Senpai went there while she was boxing with Nagatoro, thus distracting the latter and leading to her being knocked out with a single punch. Embarrassed, the girl accused him to having followed her there calling him a stalker, only to be scolded by Gamo-chan not to "rough up" her costumers, thus prompting Nagatoro to reply she invited him only to prank her. Later, Senpai told Nagatoro that he performed badly at the school's last judo tournament, thus asking her to teach him judo, Nagatoro blushed vividly and then sweeten up, shyly accepting his offer. After the two have changed into and done a little, Gamo-chan went to her lunch break with the other trainers leaving the pair alone and leading Nagatoro to propose  to a frightened Senpai, who was quickly overpowered and pinned to the ground, where he found himself unable to get free from her grip and is forced to surrender to the girl calling her "too heavy" for him to move, thus offending Nagatoro, who angrily explained that "even a light little girl like her could pin someone to the ground by controlling her own center of gravity". Later, Senpai watched Nagatoro's amazing performance during a second match with Gamo-chan. Afterwards, while walking back home together, Senpai finally asked Nagatoro if she did judo, to which she replied that she used to practice it in the past but stopped as she realized that there are "people she simply couldn't beat". Seeing her so sad, after parting her goodbye, Senpai yelled to Nagatoro that he thought her moves were "really beautiful" leading her to blush and smile at the same time before quickly run off.

Few days later, the President called Senpai at the school's judo hall due to Gamo-chan and Yoshi told her that he have been receiving training in order to compete in the upcoming judo tournament, thus she decided to give him an hand. As they got into position, however, the boy noticed that she's not wearing anything undeneath her judogi which distracted Senpai as the President slammed him to the ground. Meanwhile, after her friends told her what was happening in order to tease her, Nagatoro misunderstood it in a sexual way and reached for them finding Senpai pinned to the floor under the President's massive breasts. Afterward, the girl offered to train Senpai personally, yet he declined, informing her that Nagatoro was already teaching him, much to the latter's joy.

Then, exiting the school, the President met with a girl very similar to her.

Trivia

 * This episode is the adaptation of Chapter 67, half of 76 and 77, as well as Bonus 18 and Volume 7's back cover story, however there are a few differences:
 * The events at the beginning of the episode are set earlier in the manga - Chapter 67 - leaving Senpai questioning Nagatoro's mysterious stand for about ten chapters; the anime adapted them by placing it right before continuing those of Chapter 76, that began in the previous episode.
 * GAMOU Fighting Gym's exterior design is slightly different, as the windows are much smaller and far from the ground rather than being french windows.
 * Sunomiya is introduced this episode, while in the manga her first appearence is way later.
