A3! Season Spring & Summer

Both anime are about acting and becoming an actor. In both series, each character has their own motivation to become an actor, and they work together to get better for the final performance.  

Both anime are about a group of cute guys becoming friends and bonding over a special interest (sanrio/theater). Both anime have the theater element. 

Anime about theater actors were rare nowadays. Luckily, these shows presented in all-male characters and all-female characters within their perspectives. Each characters designed to have their background story to be told that made them as an inspirations towards on the passion of acting. 

A bunch of guys with eccentric personalities working together towards a specific goal. One anime is about football, the other about theater, but they share similar vibes. Anyone who likes cute 2D guys will likely enjoy both animes to some degree. 

Although Idolish7 is an idol anime- the formula is very similar to A3. Both stories don't focus on romance at all and instead focus on a female character helping a male cast get better and achieve their dreams while the male cast gets closer and become friends throughout! A3 does focus more on the acting and getting better more than Idolish7, while I think Idolish7 focuses more on the friendships, drama, ect between the guys. 

Both anime tell the story of a theater group that used to be really famous in the past, but now it's about to go bankrupt. A new group of actors/singers gather to try to revive its fame.  

The two shows are about acting in a theater setting and both target a female audience. 

they come from different backgrounds, ages and professions, but they are dying to perform for the crowd. they have to start from scratch with a tiny agency and make their way to success.
