Good story. The immortal part was a nice gimmick to this anime. It was used well until the end when the anime had the immortals die. Being immortal kinda means you cannot die so in it if an angel or God wants you to die you still die. It did not work in the last episode which Akane was able to kill herself to get to Hell to help the others in the harem. The relationship building between Seiji, Akane, and Yuzu was interesting. Guri was not on screen alot though when she was it was for a comedy reason most of the time. 1thing i wanted to happen that didn't was Seji getting with his sister Aqua.
