Dangerous Calligraphy

Exploration Stage: Bamboo Grove
From: Detective
Description: Why is the onryo so sure that the evidence we found isn’t related to her death? She’s following me closely and seems so furious she’s going to blow. Hmm, maybe her life was ended in an explosion? I’ve heard of a trick... Let’s find an inkwell to test my theory.
Completed: There’s an explosive mixture in this inkwell, which can blow up if you shake it, so be careful... Ugh, the onryo knocked the inkwell out of my hands! Is everybody okay? We need to get rid of the aggressive ghost right now before she kills someone herself. Let’s go see Hanako.
