The Hill Dyed Rose Madder

E1. The Scarlet First Kiss

Whilst walking in the evening, Yuuhi is saved from two guys trying to pick her up by Jun'ichi, going away only knowing him as "the Geno Killer". The next day at school, when Yuuhi transfers into Jun'ichi's class, both are surprised to see each other again so soon. During a discussion with Ayanokouji, she asks Jun'ichi out, shocking the class. It then turns out only to be for a cup of tea, which is how she wanted to express her gratitiude. She learns that he was a former delinquent. The following day, Yuuhi is pressed for details with regards to her first encounter with Jun'ichi, and in his confusion on clarifying matters for the class, Jun'ichi kisses her, only to get beaten up for taking her first kiss. That evening, Yuuhi turns up at the Nagase residence, stating that she is moving in as Junichi's fiancee, much to his and Minato's surprise.

E2. The Scarlet Approach

A scene from Yuuhi's past provides some background on the arranged marriage between Jun'ichi and Yuuhi and to her moving in with him. Yuuhi and Jun'ichi have trouble adjusting to living together, and Yuuhi spends her first night sleeping on the couch. The next day afer school Yuuhi goes grocery shopping with Minato for dinner. Yuuhi is amazed by the supermarket and by Minato's shopping savviness. That evening after supper the Nagase residence loses power and Yuuhi trips in the dark and falls on Jun'ichi leading to another very awkward situation. Minato resets the breakers and power is restored, but Yuuhi blames Jun'ichi and puts him into a headlock, which leads to another awkward situation. Yuuhi ends up sleeping in Minato's room and the two girls are able to talk and become better friends.

E3. The Scream of Bizzare Colours

Jun'ichi's teacher Seijirou Sugishita goes missing in an abandoned portion of the school. The student council president Mitsuki Siina enlists Jun'ichi and his friends to search for him in the abandoned school building. While searching Jun'ichi and Yuuhi fall down a trap door into a pit. The two are forced to work together to try and get out, but are unable to escape. In the same pit Mr. Sugishita wakes up from under a blanket and the trio are found shortly afterward by Minato.

E4. Mad Party of Indigo Blue

Karen Ayanokouji, Jun'ichi's classmate, invites him and his class to her casual "home" party. He is at first not interested, but is dragged along by Minato who also receives an invitation. When they arrive Jun'ichi, Yuuhi, and company find that the party is actually a formal event on a huge cruise ship. Seeing how underdressed everyone is Karen loans them some formal wear, and Minato makes quite the impression on Jun'ichi when he sees her with her revealing dress. This causes Jun'ichi to have awkward feelings about his sister and asks her to cover up. Later, on their way back from the ladies room, the girls discover the kitchen is seriously behind schedule as most of the cooks are seasick. This prompts Minato and the girls to swing into action to save the party. The girls finish the feast and Minato puts on a show slicing up a tuna. Karen, feeling upstaged by the tuna show, puts on her own performance fighting against a giant octopus. This sends a scared Yuuhi running out onto the deck where she trips and activates the fireworks, which ricochet throughout the ship causing a fire in the party hall. Everyone escapes safely except for Minato and Yuuhi, and so Jun'ichi goes into the fire to save them.

E5. The Scarlet First Date

Jun'ichi asks Minato to see a monster movie with him, which causes Yuuhi to become angry that Jun'ichi never thought to include her. Just before the trio are about to leave, Minato fakes a phone call and makes up a lie about a previous commitment she forgot about and cannot cancel, forcing Jun'ichi and Yuuhi to go on a date. While the two are out Minato decides to go shopping. After the movie, Yuuhi accidentally walks into a man, spilling her food onto him. Jun'ichi quickly comes to Yuuhi's rescue again and saves her from the man and his friend. Jun'ichi and Yuuhi continue with their date, but are caught by Mitsuki in the park, and are forced to make a quick exit to avoid Mitsuki's questioning. On their way home, Yuuhi's hat is blown onto a rock by the side of the river. Jun'ichi goes to retrieve her hat but accidentally falls in, sending Yuuhi into a panic. Yuuhi rushes them home in a cab and frantically searches the house for medicine and blankets. Minato comes home soon afterwards and cures Jun'ichi with some instant ramen. The next day, everyone at school is talking about Jun'ichi and Yuuhi's date thanks to Mitsuki and Nagomi (who was also at the movie).

E6. The Golden Yellow Montagne

Karen invites Jun'ichi and his school friends (including their teacher) up to a mountain hotel resort to make up for the events of the cruise ship party. While there everyone continues to hang around and tease Jun'ichi who is not impressed by their company. Karen takes this to mean that Jun'ichi is not satisfied with the luxuries of the hotel and so she takes the group on a long hike up to the Ayanokouji family's secret hot spring. There they learn that the secret hot spring is a co-ed bath, which causes some problems since the there are guys and girls. This is shortly interrupted by the sounds of a beast, and Minato takes off to find out the source of the noise. Jun'ichi, worried for his sister, follows soon afterwards with the rest of the group in tow, only to find Minato bathing in the hot spring with a bear and cub. The bear and cub leave and the group go in for a dip, boys on one side, girls on the other, and Jun'ichi tries to deal with his urge not to peek on the girls. Jun'ichi ultimately gives in, but finds that the girls have already left to interrogate Yuuhi about her relationship with Jun'ichi.
