I do not know why it's so dissed/underrated this S2 :/ Definitely one of the best ecchi harem best succeeded so far because it has combined important topics such as the faith and the superpowers of the mc in the isekai making the fanservice an integral part going hand in hand with the plot, the S2 anime counterpart - it is said around - is kinda rushed especially at the end but being in 10 eps everything is fictitiously decently, not to mention the fantastic opening & ending of/and voice actors' work! it was very pleasant and for sure it will be material for otherseasons being not even halfway light novel in progress, so it will be an "Arrivederci" Diablo-sama!
