The iDOLM@STER, Love Live! School Idol Project 2nd Season Recommendations
Love Live! and The iDOLM@STER both have idols with the purpose of reaching their goals, mostly becoming the #1 most famous idols in the entertainment business; have a lot of Slice Of Life elements with comedy and music sprinkled on top of them and have origin stories behind some (if not all) of the characters present in the animes.
Only difference between The iDOLM@STER and Love Live! is the fact that the former is based on the namesake video game series only released in Japan, while the latter is a multimedia project with Sunrise and Lantis.
Both animes are about an idol group trying to reach their goal to become the Top Idol. Not only by working hard, but also by having fun together, getting along together and by uniting each person in the group to overcome the troubles ahead. Also both animes gives us some great musics/songs and dances to enjoy.
