Chapter 1: My Big Sister is a Denpa, a Maiden, and a Holy Angel Edit
(Point of view: Hinata)
Hinata has always thought Kuroneko as being an otaku without friends. Kuroneko has been engrossed in games, manga, anime and novels since she was young. Hinata was concerned that her actions were becoming more strange as Kuroneko wrote her own novels and manga, wore a goth loli dress, and called imaginary friends on the phone.
When Hinata asked Kuroneko whether she had a crush, Kuroneko answered, “Kyousuke”. However, despite her descriptions, Hinata believed that Kyousuke was an imaginary boyfriend. Kuroneko also showed her contact list on her phone to prove she has friends, but many of the names are fictional names such as “Nine tailed fox” or “Asura bird of prey”. Hinata is becomes more worried about Kuroneko’s future.
Kuroneko began to show signs of having a boyfriend, such as making a bentou for him, and designing an angel costume. However, Hinata didn’t believe she had a real boyfriend until, one day, Kyousuke came to their house. Hinata was surprised and got to know Kyousuke while Kuroneko was taking a shower. When Kuroneko returned, Hinata teased her which led Kuroneko to become angry and beat Hinata.
Later, Hinata saw the depressed Kuroneko after returning from the firework display. Hinata correctly suspected that Kyousuke and Kuroneko have broken up.
A few days later, Hinata meets Kirino, who is excited upon meeting Kuroneko’s cute little sisters. At the hot springs, Kirino’s siscon “beast-mode” causes her to say, "Two little sisters! Wahhhhhhh! Wowwwww! Here I come -----!". This scares Tamaki.
Chapter 2: Midnight Girls' Talk Edit
(Point of view: Kirino)
At the onsen changing room, Kirino is lying down, dizzy from the hot springs. She is still obsessing over Kuroneko’s little sisters. When Kuroneko comes in, she offers Kirino some iced tea. Kuroneko says that even though Kirino scared her little sisters, she can still be with them as long as Kirino holds back. Kirino then asks if she can sleep with Kuroneko’s sisters that night.
To prevent Kyousuke from harassing his sister, Kyousuke shares a room with Kuroneko’s parents and Hinata, while Kirino, Kuroneko, and Tamaki share a different room. Kirino had been worrying the whole day whether Kyousuke would be alright in Kuroneko’s parent’s room. Kirino also reflects on how she didn’t understand Kyousuke before, but she has begin to recognize his human side in recent interactions. Kirino is glad that Kyousuke is able to stand by her side.
Hinata then runs into the room, saying, “Kousaka-kun is really cool!”. She then jokingly says that she will marry Kyousuke so that Kirino will become her sister, which shocks Kuroneko and Kirino.
Later, Kirino states that Kuroneko isn’t capable of having a boyfriend, based on the recent events, but Kuroneko intends to prove Kirino wrong by getting one.
Chapter 3: My Little Sister Can Be This Cute Edit

But Sena quickly became angry when she found out that Kouhei opened one of her packages, revealing that she wants to research game development. Kouhei was quick to apologize and kiss up to his sister.
Another time, Kouhei was doing exercises in his room, when he suddenly felt that he was being stalked. He opens the closet door and accidentally grabbed Sena’s breast. She became angry at first, but calmed down quickly because she had also been caught hiding. She revealed that she was drawing and used her brother as a model. While Kouhei was happy to hear that he was a model for his sister, he soon found that the drawing of him was bald and gay. Sena wanted Kouhei to be gay, and saw potential in him due to Kouhei not having a girlfriend, but Kouhei denied it.
Later, he walks home with Kyousuke. They talk about their little sisters and start an argument on who has the cuter sister. The next day, at the school, they enter a competition to prove who has the cuter sister by presenting photos of them. Kouhei shows personal pictures of Sena, while Kyousuke primarily uses fashion magazines. They present pictures of them in different poses and clothing. In one magazine, Kouhei sees Ayase, and he agrees with Kyousuke that she is pretty.
After the school, they continue the battle. Kouhei plans to use more pictures from home and Kyosuke texts his sister for a picture. Then, Kyousuke says that the major weakness in Kouhei’s photos were the lack of himself in the pictures. Kyousuke presents the photo booth picture on the back of his phone, and Kouhei accepts defeat. However, Sena has been listening to them the whole time. She tells Kyousuke to prepare his camera, then kisses Kouhei. Kyousuke later explains to Kirino that he lost because Sena kissed Kouhei.

The glasses helped her create a new personality, Saori Bajeena, and gain her current friends.
