— Aria

Aria (ありあ), known by most of the characters as Cha (ちゃ) or Advisor Cha (ちゃ顧問 Cha-Komon) due to the sound he makes, is a side character in the Amanchu! series. He is a cat that resides in Yumegaoka High School.


Cha is first seen in chapter 1 of the Amanchu! manga. Cha is owned by the The Principal of Yumegaoka High, but is a free-roaming outside cat who spends most of his time around the members of the Diving Club who he follows anywhere they go, including outside of school grounds on car trips. When Hikari Kohinata and Futaba Ooki first met him, Hikari mistook him for the diving club advisor, and refered to him as Advisor Cha (ちゃ顧問 Cha-Komon) thereon after. Anywhere Cha goes he finds something fun to do, be that bothering the diving club members or making his own entertainment by rolling around. After the principal adopted the stray cat Ohime, Cha became her protector, and he dedicated himself to making sure she wasn't in any danger.
