Summary
As soon as it hits 6 am, Inani jumps off of the top bunk and swiftly gets changed. She approaches the bottom bunk and awakes her brother. Begrudgingly, he gets ready and is waiting by the door. Inani grabs a paper bag of her lunch off the kitchen countertop, says goodbye to her mother and runs through the door past Masayoshi. Masayoshi runs after her and they walk to school together. As they arrive at the school, Masayoshi goes away with some older students to his class while Inani waits with her friends. After enduring a school day, Inani rushes up to her brother's classroom. He exits the classroom talking to a girl when Inani throws confetti on him. Masayoshi joins Inani and they walk home together. It cuts to night and Inani lies down, she says goodnight to her brother and sleeps.

The next morning, Inani wakes up and realises it's already 9 am. She quickly rushes out the door without Masayoshi. She enters the administration office to sign in late. Disappointed, Inani rushes back to class and waits until the day is over. Like routine, Inani waits outside of Masayoshi's classroom. After waiting several minutes, Inani looks inside and doesn't see anyone. Inani goes home by herself. Inani opens the door and confetti hits her face. She sees Masayoshi standing above her. After questioning him, Masayoshi reveals to Inani that he graduated and that he's going to be moving for a few years to study abroad. Inani tries to talk him out of it but he hands Inani tickets and says that he's already booked. Inani glances at them and sees that the date is tomorrow. Inani tells Masayoshi off for late notice and he consoles Inani. He kneels and pets Inani on the head. It cuts to night and Inani goes to bed in her school clothes. Inani says goodnight to Masayoshi just before sleeping.

When Inani wakes up, she sees Masayoshi packing his suitcase. She sighs and goes downstairs to the kitchen to eat breakfast. Masayoshi goes downstairs, rolling a briefcase and opens the door. Inani waves to him as he passes through it. Inani leaves for school. She goes through the day acting a little distant. Once it's night, she changes into a white dress. She approaches her brother's dresser and pulls out a black jumper. She slides it on. A white card falls out from one of the pockets. Inani picks it up. On the front are three katanas printed in black. There is nothing else on the card. Inani places it back into her pocket. Inani climbs up and sits on her bed. She says goodnight to her brother again but expects no response. She yawns and falls back onto a box where her pillow should be. She holds the back of her head and turns to see an upside-down cardboard box. On the top is a note reading "Niji, the Rainbow Cat, from Mayo". Inani sees a rainbow glow emanating from the bottom. She closes her eyes but opens one slightly and pulls the box open. A grey cat pounces on Inani's face, pushing her off the bed. She falls on her back and holds Niji in the air. She then says "So your name is Niji?". Inani glances at Niji's fur and says "...are you colourblind, brother? Rainbow cat, huh." She looks into Niji's eyes and smiles. She then tells Niji that they're going to be the best of friends, however, before she can finish, Niji scratches her face. The camera pans out and shows a bird's eye view of Inani's house. Masayoshi's reflection fades in. The camera zooms out and shows Masayoshi on a plane. Masayoshi holds out a collar in his palm before clenching it. He says "Inani, don't let me down" before it fades to the credit sequence.
