The first scene on this list takes a bit of a departure from what you would consider an average ecchi scene. When everybody decides to get jobs to pay for a trip during summer vacation, Yukana Yame, Nene Fujinoki, Yui Kashi, and Kokoro Shīna get a job at a cafe. Af first we see the girls cosplaying in different outfits as they continue to work there, but the longer they work, the more their perverted manager has them do. Ultimately, leading them to have a special day at the cafe where the girls will read to the customers. The girls begin to read the books out loud to Junichi, who had been working in the kitchen at the cafe, only to find out they were naughty books. Each girl takes turns reading a different book while Junichi listens and gets embarrassed.

The strength of this scene is the reliance more on the dialogue than the characters, standing out from the typical scene you would see in an ecchi anime. It’s a nice departure from how the series used fanservice, mixing it up enough to make it stand out from the rest of the series, especially with the scene coming at the end of an episode that was filed with the girls wearing various revealing outfits. The scene also benefits from having all four of the girls being around, which isn't something that happens often outside of episodes 7 and 8. While it may not be the most visually stimulating, it is one of the more memorable ecchi scenes in the series.

The scene starts off with Junichi lying in bed when he is mounted by his naked childhood friend Nene Fujinoki. Junichi tries to look away from Nene and asks her to leave the room, but she is very insistent on spending the night with Junichi. While Nene tries to get Junichi to sleep with her, Junichi has a battle in his mind between the manifestations of his perverted self and his cool self. With his cool self winning the fight within Junichi, he tells Nene he can't sleep with her due to his love for Yukana. Although Nene protests at first, she eventually leaves and still resolves to win over Junichi. This scene has everything you could ask for out of an ecchi scene. This scene is great not only because it has some of the best ecchi in the show up to this point, but also comedy, character development for both Nene and Junichi, and most importantly a good canonical reason to explain why the ecchi is taking place.

After hanging out with Yukana and Ranko, Junichi is walking home thinking about how it seemed Ranko got in his way every time he got close to Yukana when he hears somebody shout his name. When Junichi looks up, he sees Ranko standing in front of his house, confesses her love and pulls Junichi inside. After a little bit of talking, Ranko throws herself onto Junichi offering to sleep with him. While Ranko is using her assets to try and persuade Junichi to accept her advances, we get some interesting camera angles that add to the provocativeness of the scene. Junichi ends up turning down Ranko because he only wants to be with Yukana and we learn that Ranko loves Yukana and only wanted to trick Junichi into being in a compromising situation that Yukana would see and break up with Junichi.

Now that it's summertime, the girls, Junichi, and Junichi's friends have saved enough money from working to go to the beach and then spend the night at a hot spring. After a day full of fun, the girls decide they will all go bathe in the outdoor hot spring together. That's when we are treated to the nudeness and at times, lewdness of Yukana, Ranko, Nene, and Yui in the bath together. They end up discussing friendship, relationships, and some more risque topics. While all this is going on, we are also treated to a nice comedic side plot of the boys trying to peek in on the girls.

If you're looking for a scene with a good amount of nudity, this is the scene for you. With an almost constant barrage of panty shots and sexual innuendos coming at you, the bath scene loses some of its impact. Overall it's still a great filled with a huge amount of fanservice and it has some slightly more serious moments with Nene and Yui starting to come to terms with Junichi being with Yukana. However, none of that overshadows the ecchi going on in the scene giving you plenty of time to enjoy the view.

The karaoke date scene between Junichi and Yukana is not only the best ecchi scene in the series, it is also just one of the best all around scenes from the entire series. Yukana invites Junichi out on their first official date as a couple. While Yukana is singing, Junichi takes the time to fantasize about different situations he can get in while they are doing karaoke Yukana after getting relationship advice from his friends. During the various fantasies, Junichi is having a battle in his mind with the manifestations of his perverted and cool self that provides additional comedy and action to the more ecchi parts of the scene. With the perverted Junichi winning, Junichi tries to kiss Yukana, but she gets too embarrassed and leaves the room.

The aspect that sets this scene apart from the other ecchi scenes in the series is how it provides us with a huge amount of character development for Yukana. Through the first two episodes of the series, Junichi and his friends talk about how easy it would be to gain experience with a gal girl do to their promiscuous nature, but as we learn at the end of this scene, that couldn't be further from who Yukana is. Yukana may have the outward appearance of the kind of person Junichi and his friends thought she was, on the inside, she is shy when it comes to anything to do with love. With this added character development and the comedy from the inner Junichis, the scene stands out by being more than just your average ecchi scene.
