Aran is shown to be a mature, third-year student. Despite his mature appearance, Aran is often stuck dealing with his teammates' antics and, as such, is roped into playing a "tsukkomi"—straight man—like in mansai comedy routines, as he reacts to whoever is acting as the "boke," or funny man; he is always quick to react to nonsensical things his teammates say with comebacks, such as "What does that even mean?!"

Aran believes that you don't need logic to feel things such as happiness, and he's quick to snap that at Kita when he wonders whether him becoming the captain is just a side effect of his everyday actions or is a result, saying that "You don't need a reason to feel what you feel, if you're happy you're happy, and that's that."

While Aran is known for being mature and levelheaded most of the time, he is shown to occasionally become too fired-up when playing in a match which tends to result in him rushing a play or putting too much power into an attack. Despite this, he does show that he can quickly calm himself when he is getting too riled up.
