HP]https://misutosho.shufunotomo.co.jp/ ■Synopsis My name is Takagi Towa. I’m in the sixth grade. I transferred to M Elementary School in the fifth grade, and I still haven’t fit in with my class… I’m an outsider in my class, but I’m best friends with Nakagawa Sae, who’s also an outsider! People say I’m weird at school, but when I’m with Nakagawa Sae, I don’t care. That’s because Nakagawa Sae has excellent grades and athletic ability, and she’s a cool girl who can argue back with reason even when classmates and teachers say unreasonable things to her. And he’s a great detective who never misses even the smallest anomaly! A cat cafe full of strangeness, the true identity of the mean teacher, the truth about Urashima Taro… When you’re with Nakagawa Sae, your ordinary daily life becomes filled with mystery. This is the story of a mysterious incident that Nakagawa Sae and I experienced before summer vacation.

It’s also worth noting that this story realistically reflects the surprisingly harsh world sixth-grade girls live in! ■Author Gen Kato I grew up engrossed in the “Boy Detectives” series and “Pippi
Longstocking.” So I’d always wanted to write a story that would captivate children like me, and when my editor approached me, I was thrilled to write it. (From the “Mystery Library” website, Author’s Message)
