I bought this book on a sale from an online book outlet site expecting this to not amount too much. A girl transferred to another world with a bear onesie that makes her stronger. It's ridiculous and no way that it amounts too much is what I thought. Not surprisingly it isn't very deep, but I couldn't stop reading. It was just plain dumb fun, and sometimes that's all you need. Yuna is embarassed but realizes she can't do anything about the bear onesie and the bear theme surrounded all her powers. If you go in looking to be entertained, it will do that. If you're looking for a deep story, this won't be it unless it manages it in future volumes.
