Episode 10

"You Seem Pretty Stiff, Senpai/I'll Do It For You, Senpai!" (センパイって体、硬そーですよねぇ/やってやりますよ、センパイ！！) is the tenth episode of the Ijiranaide, Nagatoro-san anime series.

Plot
Nagatoro asked Senpai if he wanted to see some “hot snaps” describing them as "cool" and "all natural", prompting the boy to imagine it were naked pictures of her, however Nagatoro quickly revealed she intended Snapping Hot Chicken accusing him of being a pervert because of his thoughts.

Later, Nagatoro and her friends watch from their classroom window as the second year students were having a marathon, immediately spotting Senpai and marveling at how poorly he was performing, since he was way behind everyone else. After classes, Nagatoro went to Senpai and playfully told him that, as his kōhai, she was embarrassed for him, however when he replied that "all he can do was draw" she was greatly bothered, getting so motivated and angered by his lack of self confidence to begin personally train him. The following day, despite being a weekend, Nagatoro forced Senpai to join her in the marathon training, showing up with her hair in a ponytail as well as wearing a skin-tight skimpy top and short, turning on the introverted boy who couldn't help but stare at her sweaty and barely covered behind while running their 5Km route. This caused Senpai to up his pace in order to stay in front of Nagatoro and not risk being accused of perverted thoughts. After covering half of the route, Senpai collapsed and asked Nagatoro to stop, causing her to insult him to provoke him, going as far as to slap her own butt telling him to try to catch her if he was angry. Senpai reprised the run angrily, causing the girl to smile and sweetly tell him to do his best.

Eventually Senpai managed to run all the way the 5 km route of the marathon training and Nagatoro told him to do some stretching; however as they stretched she noticed how stiff was Senpai's body, suggesting him to do a forward bend and showing him how to do it, thus causing him to vividly blush as he was having trouble the entire day not to gawking at Nagatoro's butt. Since Senpai's body began to shake, Nagatoro started to help him doing the exercises in pair until his body got more and more flexible. However while they were doing their last stretching position, Yoshi passed by while walking her dog and, seeing them, asked if they were trying the fusion from , embarrassing them both.

Sometime later, with the Culture Festival getting closer, Senpai has trouble finding someone to model for him. Overhearing as he was having said thoughts out loud, Nagatoro made Senpai explain everything to her with the intention of being asked to help him, however the boy refuses to use her as a model since he considered it too hard to draw a female figure. Due to the girl insistence, Senpai eventually decided to tell her he would have used her as a model only if she posed cosplaying in her infamous Nekotoro version, sure that the girl would be unable to find said costume or in any case too embarrassed to wear it. The following week, much to Senpai's surprise, an utterly ashamed Nagatoro showed herself into the art club room wearing a perfect Nekotoro costume that she asked the handicrafts club to make her. The girl insisted that he say something and got really mad when he simply complimented how the outfit was well made.

Meanwhile, Gamo-chan, Yoshi and Sakura peered into the room; then they joined them as Nagatoro posed for Senpai's painting, teasing him to make her look sexy or mocking him for his embarrassment. Later, the girls started to chat regarding what they planned to do with their clubs or class for the Cultural Festival, then, while asking what would be the art club exhibition Senpai stared into space and began to remember: The previous year, while still a freshman in high school, he helped the zealous President of the club to organize the art display for the previous Cultural Festival's exhibition, which is revealed to be a huge success; the boy indulged in how much he admired the driven, charismatic and amazing person that she was and how the last day of their exhibition she thanked him for having allowed her to have some good memories before having to go to cram school like all the second years, thus becoming unable to join club activities anymore and leaving the art club to him. After Nagatoro woke him up from his memories, Senpai answered that he would probably make an art display like the previous year, causing the girls to say it would be boring and that they would give him a hand to fire it up a little. Nagatoro ironically suggested it would be fun to have games in which he gets tortured or a kitty-themed while Sakura suggested a cross-dressing café featuring Senpai dressed like a female maid, which a secretly amused Nagatoro refused, fearing the boy could get too much attention. In that exact moment, Senpai heard some familiar footsteps and asked the girls to hide in the prep room right before the President entered with a stern expression.

The President told Senpai that she would also help the art club display by submitting also one of her paintings, then she scolded him for some rumors she heard about the club room having become a hangout for a bunch good-for-nothing. In the meantime, while eavesdropping on their conversation hidden in the prep room, Sakura, Yoshi and especially Gamo-chan all teased Nagatoro saying that beautiful older girl is probably Senpai's ex. While the President told Senpai she was disappointed for him inviting people and being rowdy, reminding him that the art club was not a playground, the still-hidden girls felt kind of sorry and apologized, although only internally. The President, also saw Senpai's painting of Nekotoro and criticized it, saying this wasn't the manga research club, then informing him that she spoke with the student council and was thinking about disbanding the club. Due to Senpai being unable to reply, Nagatoro came out of the prep room with her friends and faced the President herself accusing her of being selfish and unreasonable as she was the one who abandoned the club only to suddenly walk back in it talking about disbandment. The President dismissed said accusation stating that if the only club member lacked motivation there were no reason for the club to continue, thus angering Nagatoro who finally lashed out making her feelings for Senpai transparent and yelling that even by himself he has always worked really damn hard. Hearing this, the President suggested that Senpai should hold his own art display independently from the club and, if he defeated her display in the school's popularity contest she would have rescinded the club's disbandment. Although Senpai was not very confident about it, Nagatoro immediately accepted the challenge in his stead.

Trivia

 * This episode is the adaptation of Chapter 30, 36, 37 and 38, as well as Bonus 8 and Volume 1's back cover story, however there are a few differences:
 * During the marathon for the second year students, Senpai and the others runners are wearing a tracksuit in the anime. In Chapter 30, he simply wore a t-shirt and running shorts. Also, in the anime, when Senpai meets up with Nagatoro for practice on the weekend, he wore an unzipped orange hooded sweatshirt over his t-shirt in the anime; in the manga, he wore a t-shirt.
 * After Yoshi sees Nagatoro and Senpai stretching together and asks "Fusion?", in the manga, Nagatoro yell out "No!", while in the anime, the eyecatch appears immediately after Yoshi's line.
 * When Senpai explains the story of Ikkyu-san and The Tiger, in the manga, the animal is shown as a regular tiger, Ikkyu-san as a young bald monk and the Lord as a man with a long mustache. When he imagined it in the anime, the tiger has Yoshi's likeness, Ikkyu-san is played by Senpai and Nagatoro plays the Lord. Later, after Senpai realized that his plan has failed, in the manga, the tiger is shown leaping out as Ikkyu-san backs up. In the anime, the tiger jumps out and lands on Ikkyu-san, before proceeding to bite down on the top of his head.
 * In Chapter 36, when Senpai has to find a model, in the manga, it shows that he already had a male model who had to back out at the last minute and apologizes to him before leaving the room and later he explained what happened to Nagatoro. In the anime, it starts with Senpai already debating who to get as a model before Nagatoro enters the room and it is ambiguous whether he had asked anyone beforehand.
 * When Nagatoro pulls out the drawing that Senpai made of her in the Nekotoro outfit, the manga version shows that it was drawn on a clean sheet of paper and that one her paws is bent forward in a beckoning motion. In the anime, it appeared to be drawn on lined notebook paper, similar to what was seen in Episode 6 and the bottom of both paws are visible.
 * In the manga, as Nagatoro gets mad at Senpai for complimenting just her outfit, only Gamo-chan and Yoshi were looking at them from the corridor, while in the anime Sakura was there too.
 * When Nagatoro asks Senpai to draw her sexy, in the anime, she remains standing in her pose as she and the other girls explain what their clubs or classes will be doing for the festival and doesn't sit down until she rejects the idea of Senpai crossplaying as a maid. In the manga, after her request to Senpai, she takes a seat with the girls while talking about the club activities and remains there until she and the other girls make suggestions for Senpai.
 * When Nagatoro explains that she will be making yakisoba for the swimming club, in the anime, she is wearing light colored clothing and has a bandana over her hair, while in the manga, she wore dark clothes and didn't wear a bandana.
 * After Sakura tells the group that she will be helping the video game club after making amends with them, in the anime, it jumps to Nagatoro asking Senpai what will the art club being doing; in the manga, Sakura further explained that the video game club will be doing a VR experience booth for the festival and suggests that they all stop by before Nagatoro asks about the art club's plans.
 * When asked by Nagatoro why she joined the games club, in the manga Sakura explains her life philosophy, according to which "mankind are all brothers and sisters" and "should all make up and have fun", while in the anime she simply answers that she became friends with them.
 * During the flashback sequence of Nagatoro's ending speech it was retroactively revealed that she was actually awake when Senpai managed to draw her for the first time in Episode 4, while in the manga she was asleep all the time until the end.
 * After Nagatoro defends Senpai, in the manga the President says that she understands what Nagatoro is trying to say, but she cannot just let things slide because of the student council's warnings, and so she thinks of the challenge for Senpai to prove himself. In the anime, the President goes straight to proposing the challenge for Senpai.
