Tsuyokiss

Both High school animes but Kanon (2006) varient is able to one up this anime by story because the series makes you want to watch from begining to end 

Both of the main characters work hard to reach their goals.  

Comedy, romance, drama, and stage acting/movie filming what else could you ask for more? Both of these series are great for anime fans who enjoy a slow paced yet meaningful story. Ano Natsu does has a sci-fi side that Tsuyokiss lacks. However, both series are little gems that any anime fan should add to their collection. 

Eri reminds me, well, of Eri in Tsuyokiss... It's kinda strange but you'll be able to see the resemblance Plus, they're both very funny... :p 

Both shows are about a girl trying her best to make a new club in her school. While the clubs get rejected a few times at first, neither girl gives up! 

The highschool romance...drama...ENJOY =3 

Both tell stories of a uselessly energetic student fighting against the injustices of school bureaucracy. 

Both are about a girl that wants to establish an drama/acting club at her school because there isn't one anymore or never existed one. While Tsuyokiss choose a tsundere to take the lead role, Clannad takes a light hearted and silent heroine who depends much more on her friends instead of her own strong will.
