Anne Happy's pretty cute.
Have you watched Gakkougurashi! (School-Live!) yet?
It has a similar aura, but can be quite surprising.
ReLIFE is really good, Crunchyroll added all 13 episodes at once on July 1, I Started Rewatching The Series On July 6.
I just signed out of my Funimation account to check, and it's only available to subscribers at the time, but I'm pretty sure that after the episode has aired for a week they release it online with commercials.
Love Live: Sunshine airs is updated on Saturdays, so it should be available for non subscribers on Sunday.
I just got the code for the Crunchyroll 48 hour pass, do you want me to hold onto it until the entire series has finished airing?
