Complete Edition: Takao Amaku's Case Files & Reasoning Files by Mikito Chinen - 4 Book Set I got hooked on this series a little before the drama started, and I've been reading it bit by bit while doing housework. I haven't finished reading all the books in the series I bought yet, but I'd love to pass them on to someone who's interested! "Kuwon no Ori" (Eternal Prison) was purchased on Mercari, so it's a little older. Mythical Locked Room - 680 yen Deadly Prison - 740 yen Eternal Prison - 710 yen Cursed Symptom - 770 yen
