I've read it a few times and kept it in storage. Retail price: 2400 yen + tax. First edition, with serial code. (The serial code has no expiration date, but please understand that it may not work if the game specifications change.) The cover has scratches and small marks as shown in the photos. The book itself is in good condition, with no damage or stains that would interfere with reading. Please refrain from purchasing if you are concerned about minor imperfections. I plan to package it with only water damage protection and put it in a brown envelope. Shipping via Yu-Packet Post from Yu-Yu Mercari.
