Free manga in kindle

I thought I set Moon and Blood 2 and Shinku Chitai (The Isolated Zone) 3 on Kindle free campaign from today, but Moon and Bood 3 instead of Shinku Chitai 3, by mistake. (All Japanese edition)

So, Moon and Blood 2 and 3 are free at the moment, but Shinku Chitai 3 will be join it from tomorrow. (Friday) It lasts for 5 days.

Shinku Chitai 5 has just been released. The price is 200yen not 100yen, it's because Amazon changed the minimum price of KDP. Manga file is large, so they think 100yen doesn't pay, I supposed.

Shinku Chitai : The Isolated Zone 5 Japanese edition ￥200
