Tate no Yuusha has reached its conclusion.
Looks like Naofumi's end was indeed a harem one, with Raphatalia, Melty and Saidina and in the alternate world he had both Atlas and Raphatalia.
Kiel is married to Fohl.
Ren is married to Eclair and Wyndia.
Itsuki is with Rishia.
Kind of sad that there was no news about Motoyasu and his three Filo Rials.
Quite sad to know that Firo and Raph-chan just disappeared after Melty's death though.
