Seiren

-Made by the same Author. -Story arcs for each female MC with the male MC. -Story resets after 4 episodes  

Similar animation style, harem genre, each heroine has her own 4 episodes ark, however Amagami's plot is more adult, but Seiren contain more fanservice 

histoire en plusieurs arc qui présente dans chacun d'eux les dernières années de lycée du personnage principale et le début d'une romance entre lui et une autre élève .Chaque arc se passe a la même période mais avec une figures féminine différente 

Both of these two Anime series consists of a male protagonist ending up with each of the female characters within each arcs to please the audience. Seiren having 4 Episodes per girl along with Amagami having possibly 4-6 episodes dedicated to each girl. (Each Arc Focuses On One Girl)  

Criado pelo mesmo autor , a premissa é basicamente a mesma de AMAGAMI SS , o protagonista quando termina a rota de uma heroina , o anime volta no tempo e começa a rota de outra garota . Se vc gostou gostou de AMAGAMI vale a pena dar uma olhada nessa 

if you like anime harem with route system then this 2 anime I can recommend. sorry for my broken english, I'm not a fluently english speaker. 

- Both made by the same person - Hikari and Haruka have similarities like good looks and personality - Both reset female protagonists after 4-5 episodes 

It uses an Omnibus format as well and is a romance. 

Both of them carry the theme of game dating (vn), there are some beautiful girls, besides the theme of youthful love is also their attraction, even though they have a different conflict but at its core this is a romantic story. 

Well, if you want a brief summary of Tsuki ga Kirei then watch the first 4 episodes of Seiren. Other 8 episodes are kind of going into a different path so I am not highly recommended.
