Tatsuya Ara is a manga artist known for creating sports-focused series, primarily serialized in the magazine Weekly Shonen Champion published by Akita Shoten. Ara is the author and illustrator of the volleyball manga Harigane Service, which began serialization in 2014. The story follows a high school volleyball player with a unique serving ability. A sequel titled Harigane Service Ace continued the series in the same magazine.

Ara later launched a soccer manga titled Campioni, with its first volume released in April 2026. This series is also serialized in Weekly Shonen Champion and centers on a young elementary school student who discovers a talent for soccer through the guidance of a school counselor. Ara's artistic style has been noted for its similarity to another manga artist, though his storytelling emphasizes a protagonist overcoming personal trauma and self-doubt through team sports.

The creator is also credited for work on the anime Ani × Para: Anata no Hero wa Dare Desu ka, an NHK project that adapts para-sports into short animated films. Beyond this and his manga serializations, extensive verified information regarding Ara's personal background or broader adaptation history remains limited.
