Kerokero Ace

Kerokero Ace (ケロケロエース) was a Japanese shōnen manga magazine published in Japan by Kadokawa Shoten. It directly focused on the Sgt. Frog series and other works promoted by Bandai such as Gundam. The magazine contained manga comics, computer game reviews, merchandise promotions and gifts.

Focus
The magazine focused primarily on the series Sgt. Frog, containing features, promotions and a new manga. The manga saw Keroro and his allies sent to an alien world which resembles feudal Japan. They are tasked with attempting to bring order to it.

The magazine's secondary focus was Gundam. Similar to Sgt. Frog, the magazine contained much promotion of its related merchandise and four of the comics running were Gundam titles. These included an adaptation of the television series Mobile Suit Gundam 00, latest chapters of SD Gundam and GPEX Gunpla Extreme, in which humans use special gadgets to shrink down and turn Gundam models into working miniature mecha.

The remainder of titles printed in the magazine alternated between comedy adventure gag comics and further promotional tie ins.
