Yako/Relationships

Hanako
Hanako as the School Mystery Number 7 has command over Yako as a leader. Yako makes little attempt to listen to his requests, only agreeing to help after Hanako threatens to make her into kitsune udon.

Tsuchigomori
Tsuchigomori and Yako have been shown bickering ever since his introduction as supernatural. He derogatorily calls her "stupid fox" or "echinococcus" while being addressed as "emo spider" as well as getting bitten by her in her fox form. Despite their constant quarrelling, they both are shown regularly interacting with each other in contrast to the rest of the seven school mysteries who keep to themselves.
