■ Comment from Futa Sakai

I am very happy to have achieved approximately 15,000 copies in cumulative circulation within two months of its launch, marking my first book. If this book has helped even a little to cheer up those struggling at work, then writing it was worth it. It's a book with an interesting table of contents, so please take a look at least at that.

■ Comment from Gunpy

Literary critic Kaho Miyake wrote a fantastic帯 (book jacket strip) comment: 'My worries are all written here!'. My worries are also all written here. It might be presumptuous to say, but it's an amazing book packed with things as universal as the 'Analects of Confucius'. It's a book I will surely reread many times in the future.

■ Book Introduction: 'Rifujin Shigotoron: A Book to Read When You Think "Screw This!!"'

A business book for the Reiwa era that is both funny and useful, presented by an expert in human resource development and the 'Bakido' duo.

This book is a 'funny and useful business book' reconstructed with significantly added information based on talks from the podcast special 'LAUGH & BIZ -Funny Business Theory on Irrationality-' broadcast on the GERA app. Reflecting on Gunpy's surprising background—including working as a Bookoff store manager before becoming a comedian—and Sakai's experiences with parental bankruptcy, hard work in a mega-venture, and entrepreneurship, the authors argue that the worries and 'irrationality' faced by workers can all be unraveled by 'theory'.

Furthermore, the book includes a column by Sakai titled 'Sakai's Supplementary Lecture'. He writes sharply, humorously, and with overwhelming passion from a unique perspective derived from vast input on topics that are problems in modern business, such as 'Mid-life crisis' and 'Brilliant Jerk'.

■ Comment from Kaho Miyake (Literary Critic)

My worries are all written here! Whether it's jealousy, shame, or burnout, somehow it becomes acceptable when Gunpy and Sakai talk about it. A must-read for troubled working professionals!
