Currently Airing Anime

Slowpiking.

Angel Beats 13:
I don't know if I'm the only one who noticed this, maybe just because it's a Key anime, but the series played out like an actual adaptation of a visual novel. Even the pacing felt like they were cutting through the other routes as side stories and giving you the "true ending" for last.

 Spoiler

At first Otonashi was introduced to Yuri, but later triggered more events with Kanade. Because he stood with her route, they went for the "save everyone by erasure" method, but I could see the story taking the opposite twist if he ended up with Yuri's story. Perhaps they'd take that deal to become god at the end, and watch over the world together, making afterlife a paradise for those who still bore regrets after death.

It'd be interesting if a visual novel was actually made for this, with other possible endings.

All in all, I would have rather seen the epilogues of other characters as well.
