“Let’s Find Wonderful Things” “Mitsukeyō Suteki na Koto” (みつけよう　すてきなこと)

Komari is in shock from remembering her dead brother Takuya, recalling the time they spent together in the hospital. In Komari’s recollection, Takuya writes a picture book for her, and tells her that he might be gone when she wakes, but tells her not to be sad because it will all be a dream. When Komari awakens, her brother has died, but she remembers what he said, and does not despair. As a defense mechanism, Komari begins to believe that Riki is her brother. Kyousuke tells Riki that if anybody can save Komari, Riki can. Riki speaks with Kojirō, who tells him that this happens every time Komari witnesses death, and that she will return to normal in a few weeks. However, Riki is determined to save Komari, and adds to Takuya’s story book. Riki forces Komari to accept her brother’s death, but through his extension of Takuya’s book, shows Komari that she has friends to support her.

She invites him up to the roof to watch a meteor shower, where the spend the rest of the night. Komari asks Riki to go on a date with her so she can search for her lost memories. They take a train to go to where Komari used to live and they end up taking a boat out on a lake. Riki suggests to her that she does not necessarily have to look for her brother, and Komari jokingly asks him if he will be her brother. It starts raining on their way back towards school, and while running to find shelter, Riki spots a dead kitten. Komari starts sobbing uncontrollably as she recalls memories of her brother.

He finds her asleep and hears her sleep-talk about her brother, but when Riki asks Komari about him, she says she is an only child and that her brother only appears in her dreams to read her a picture book with eggs and chicks. The next day, Riki and Rin go to the roof and find Komari a little sad. She had found the picture book from her dreams with the name Takuya Kamikita on the back, but her mother will not tell her anything about having a brother, and Komari cannot remember anything about him. Komari asks Riki and Rin to accompany her to a retirement home, and the other members of the Little Busters decide to join in as well. They spend time with the retirees, talking with them and cleaning their rooms. Riki cleans the room of a cross old man named Kojirō who normally scares anyone away by yelling at them, but Riki stays and cleans his room regardless.

The members of the Little Busters baseball team have morning practice, though Rin is less than enthusiastic. Masato gives Riki back his idiom dictionary, albeit damaged and smelly, in a plastic bag. Haruka Saigusa, a girl from a different class, wantonly borrows the dictionary before Riki can stop her, and upon chasing after her accidentally runs into the desk of Yuiko Kurugaya, a genius girl who is often absent from class. While during a class break when Riki is trying to buy a drink from a vending machine, Yuiko drags him away to a spot with a few chairs and a wooden box she set up among some hedges. They spend time talking, and ultimately Riki loses track of time, later dashing back to class when he hears the bell. Haruka gives Riki back the dictionary and berates him over its disgusting state under the cover. When Masato and Kengo are about to have another fight, Yuiko intervenes, causing Kengo to lose interest. Yuiko and Masato initially fight with the rules Kyousuke previously set up, but Yuiko loses after she severely kicks Masato several times. Later, Yuiko catches the Little Busters during practice and joins the team, proving to be a powerful asset.

On the school’s roof, Riki finds Komari Kamikita, a clumsy girl from his class who loves sweets. Riki tells her he wants to recruit her for the baseball team, but he soon realizes that she may not be well suited for baseball. Later, Riki goes to find Rin after she shirks her classroom duties to play with several cats. One of the cats has two notes tied to it, the first of which says that there is a secret to the world and if they want to find out what it is, they have to complete several tasks first. The second note lists their first task: Fix the sanitation problem in the boys’ dorm storage shack. Riki doubts the sincerity of the notes, but Rin is excited to take on the first task. She later gathers up Kyousuke, Riki and Masato to go clean the storage shack. Komari finds them there and agrees to be join their baseball team, but first she and the others go to work cleaning up the shack. On the baseball field, Komari displays a complete lack of athletic ability, but Kyousuke still welcomes her onto the team after she replies to his question of what is necessary for baseball with the answer, “Guts, bravery and friendship.” Soon after, Riki collapses from an attack of narcolepsy, which he has had since childhood.

Riki asks Kyousuke to intercede, who tells them to fight only with objects thrown from the crowd of onlookers. Kyousuke’s younger sister Rin objects when Masato tries to use a white cat as his weapon, causing Kengo to lose interest. Riki reminisces how he has been friends with Kyousuke, Masato, Kengo and Rin since childhood when they brought him into their group called the Little Busters. Riki later suggests that the five of them do something together like they used to, and Kyousuke proposes that they play baseball under the team name Little Busters. Kengo immediately excuses himself from this, as he has to prepare for a kendo tournament. Later that night, Kyousuke gets Rin to go to the girl’s dormitory to try to recruit team members. After a couple of failed attempts, Rin is confronted by Sasami Sasasegawa and three other members of the softball team; Rin ends up losing the fight. The next day, Riki goes looking for new Little Busters members, which leads him to follow a girl up to the school’s roof.

The next day Nao notices that Haruka tries to hide his date with her from Sora, but she just went along.

With that event, Sora becomes even more insecure, eventually telling Haruka not to leave home and tells all sorts of excuses just to make him stay. One day, Sora made Haruka choose between her and Nao, but he just shrugs it off and proceeds to school with Nao as if nothing is wrong. That afternoon Haruka finds Sora missing after receiving a text from her saying “Let’s leave here.” Akira, Kazuha, and Ryouhei joins Nao and Haruka in search of her, until, amidst the rain, Nao finds Sora at the bus stop.

Kirino gets a long awaited eroge in the post and spends the entire day playing it, despite some frustration in the beginning when one character is cold towards her. Unfortunately for Kyosuke, who is trying to study in the next room, Kirino gets really interactive with the eroge. Meanwhile, Kuroneko stays at home and tends to her little sister, who is a Meruru fan. Elsewhere, Saori plans for a maid-themed party for Kirino and Kuroneko.

By now Sora is showing her hatred of Nao in the open, even in front of Ryohei and Nao herself. One afternoon Sora, attracted by the smell of curry cooking in the kitchen, catches Haruka and Nao making love in the living room. Sora throws Nao out of the house, warning her not to see Haruka ever again, since it is the second time she catches the two doing the “dirty deed.” She then throws the curry they cooked down the drain, as she only wants Haruka’s cooking. Nao is desolate after that, and though she wants to see Haruka, she has to hide because Sora is always nearby. However, Haruka is always optimistic Sora will forgive and accept them both, as he, after knowing from Ryouhei that she changed, wants Nao to return to being a cheerful, caring, and lighthearted person. Sora lightens up a bit to the sight of Haruka and Nao being together, but still has some resistance, and prefers to distance herself from the two. It is for this reason that she never joined Haruka and Nao along with Ryouhei, Kazuha, Akira, and Motoka for the annual summer trip to the beach.
