Jibaku Shounen Hanako-kun 2 Part 2

Kamome Academy's annual sleepover arrives on the same night the boundary between the living and the dead grows dangerously thin. Nene expects a rare chance to relax with her best friend Aoi, only for hostile spirits to emerge and Aoi's presence to attract Shinigami, the Sixth Wonder whose flute can bind souls.

Shinigami abducts Aoi to use her as a sacrifice that would permanently seal the border between the two worlds. Nene, Hanako, and Akane descend into the depths of the realm of the dead to bring her back, while darker suspicions begin to surround the Seven Wonders themselves. Saving Aoi now means confronting death directly and discovering who can still be trusted within the system meant to preserve the balance.
