Omake Gif Anime - Watashi ni Tenshi ga Maiorita! - Episode 13 [OVA] - Higero Zombie

It's not surprising Hana dressed up as a Higero Zombie for Halloween, but that dance she did was surprising.

The OVA that came with the Blu-rays contained several mini-episodes. The longest one was a camping trip to the lake that Miyako did not want to join. The other very short ones showed how Koko met and stalked Miyako through the years. The Halloween vignette had the other girls dressing up as everything Miyako hoped Hana would wear, but she chose that Higero Zombie costume. And the feels train came in when Miyako first met baby sister Hinata.
