On sale now. Also listed on other sites. Please note that the item may sell out depending on the timing. This book was for a university I hoped to attend, but I changed my mind just two days after purchasing it. I only flipped through it, so it's practically unused. I've done a quick inspection, and there are no visible writings or markings. It's in almost new condition, as if it could be on the store shelf. Original price: 2420 yen. I'm selling it in hopes that someone will find it useful. Thank you!
