Message from Kairo-kun

Hello, this is Kairo-kun. Believe it or not, Kairosoft has reached its 30th anniversary this month.

Congratulations! We thought we'd celebrate by launching a Steam bundle.

It's a limited-time offer, so please check it out.

By the way, we call it 'Kairosoft 30th' because it has been 30 years since our first publication in TechWin; as a corporation, we are still in our 18th year.

We look forward to celebrating the 20th anniversary of Kairosoft Co., Ltd. in 2027.

We appreciate your continued support.
