This anime is very good, no character is considered "useless" from the episode 18, the creator made Natsuki Subaru seem pointless to hate him, even if they have people like him.
The other characters are also great art is perfect and skills as well.
Rem x Barusu - Impossible not shipp ~
The opening and closing songs are great, Konomi sings Redo, MYTH ROID sings Paradisus paradoxum and Styx Helix, STRAIGHT BET ..... Very Good
The songs of the characters are very good, I loved "wishing" of Rem and Stay Alive Emilia, on YouTube I found another of Emilia was "Dream of boy" and my God. Very good, I'm waiting for the Ram, which is my favorite character.
By the way, Rem has a nendoroid I want too ^^
The costumes are beautiful, especially the Rem and Ram, maid costume is very kawaii ♡
Do not ask why I gave 10 to all, this anime is great and goes beyond your imagination ..... I Love Much ♡
