Aoi looked out from the school window and saw Hibird flies toward her singing the Namimori anthem. Then Hibird stopped in front of her, still singing the Namimori anthem. She smiled and patted Hibird on the head gently. "Hello little one, what are you doing here? Are you not supposed to be with Hibari-san?", she asked. The bird just chirped to her. "Well you have to go back to him, or Hibari-san will be searching for you". Instead, he flew to her shoulder and started singing the Namimori anthem again.

'Where is that bird gone?' In fact Hibari was really searching for Hibird.

Aoi walked through the hall with Hibird on her shoulder, singing the school's song. Every student in the hall stared at her and asked each other why Hibird was with her. "Hibird-san, can you please lower your voice a little?". But Hibird kept singing. Then she sighed in defeat, "I guess I can't do anything about it…you really like singing don't you…I can teach you a new song later". Hibird kept singing through the hallway.

From far way, Hibari sighed,' he will come back later'. He yawned.

On the rooftop

"Nee, Hibird-san what kinds of songs do you like?", she asked Hibird. Hibird chirped in answer. "Hmmm…let's see…how about…'Okaeri'? Okay it was decided! I will teach you now, here we go…". She started to sing the song. She sang it very well, her voice was sweet and beautiful. Hibird seemed to be listening to her carefully.

After a few minutes, she finished singing and smiled to Hibird. "Now you try". Hibird started singing, but he only sang the first part of the song. She giggled and sang again to make him remember the lyrics. She seemed to be having fun together with Hibird.

And Hibari, he was in the reception room, still thinking where did Hibird go while he was doing his work.

"Finally! You did it Hibird-san", Aoi cheered for Hibird. Then she looked at her watch and it was almost time for her next class to begin. "I have to go now Hibird-san, and I think you should go back to Hibari-san is...". Then Hibird started to fly away from her, singing to the school's song. Aoi sighed, "Hibird-san still like the school's song better…oh well". She went to her next class, which was Science.

In the reception room

Hibird suddenly came in to the room and stopped in front of Hibari's desk. Hibari stopped writing and looked at Hibird. He patted Hibird and Hibird chirped. "Where have you been exactly?" Hibari mumbled. Hibird started singing the school song, which Hibari was getting used to. But the song suddenly stopped at the middle. "Un?", he looked at Hibird confused. Then Hibird began to sing again, but it seemed to be a different song. Hibari never taught Hibird that song and he even never heard that song before. He didn't stop Hibird singing that song. He just kept listening to the song and wondering where Hibird had learned that song.

'Okaeri' sang by Ayaka.

It's a very nice song (in my opinion…)
