[DeepL Translation - needs review] Do you want to be just a know-it-all?"
Rintaro Natsuki is a high school student. He has lived with his grandfather, who runs the Natsuki Bookstore. His life changed drastically when his grandfather suddenly passed away. Rintaro's aunt, whom he had never met, takes him in and while sorting through his books, he encounters a tigerneko that speaks human language behind a bookshelf. The tiger cat wants Rintaro's help to protect the books.
Poignant and poignant!...
If you liked the first book in the series, you'll probably like this one. If you didn't like the first book in the series, definitely don't read this one.
The main character changes (now a middle school girl with quite bad asthma) but the overall vibe of the book and the talking cat do not change. Difficulty wise it also felt the same.
