HSHK Chapter 11

Supernatural Cold (怪異風邪) is the eleventh chapter of the spin-off Houkago Shounen Hanako-kun.

Summary
Hanako is in the infirmary, having caught a cold. Tsuchigomori and Yako are also ill, and Tsuchigomori tells Nene about the supernatural cold. It only affects supernaturals, and aside from the usual cold symptoms, each supernatural's characteristics also become more easily visible. Being a ghost, Hanako is more transparent than usual, while Tsuchigomori is showing his inhuman characteristics like pointed ears and teeth (which he hides beneath earmuffs and a cold mask). Like the common cold, it's cured by resting. However, Hanako sits up suddenly, exclaiming that it's been decades since he caught a cold, so he's going to show Kou. Nene runs after him, only to find that Kou has thoroughly electrocuted Hanako, as he hadn't known about the cold, and thought that Hanako had finally revealed his true nature by flying at him so suddenly. Hanako hears Nene calling him as his eyes drift closed, and says that he's happy that she's worrying over him… while hugging a fire extinguisher that he's mistaken for Nene's leg. While Kou tells Nene to calm down, the Mokke arrive, having waited for the Seven Mysteries' moment of weakness, and pile onto Hanako to kill him.

Back at the infirmary, the Mokke have now all caught the cold from Hanako. Nene and Kou take care of them, while Hanako has recovered completely after transferring his cold.
