Granblue Fantasy The Animation: Kabocha no Lantern (2017)
Story
Halloween edition of finding someone lost. It turns into a really good heartfelt story. Bought a tear to my eye even.
Art
Same as the main story, set like a fairy tale come to life in a good way.
Sound
Same as the main story to which is good but also pretty standardized.
Character
Another one with the female character being used which is not a bad thing. Bit of confusion with the characters for a new one appears like she has always been there but wasn't shown particularly before and also our main character out of nowhere uses magic that wasn't from before.
Enjoyment
The episode is quite fun and has funny moments. It is nicely done and worth watching. It is a really good episode that brings fulfillment.
Overall
Worth watching and is good fan service.
