So I am a complete FMP nerd. Kaname Chidori is my favorite anime girl of all time... so you just KNOW I am reading FMP:O.
This manga is sort of a chibi take on FMP and is all about comedy... basically like FMP: Fummofu was. The downside is that the art style is also a lot more simplistic (duh, chibi). I'm up to volume 3 of the manga and will probably keep buying it. Each chapter has at least on good laugh, typically provided via Kana-chan's witticisms.
If you are not familiar with the characters of FMP then I could not recommend this series as much of its humor is derived by amplifying every-one's personalities. Souske is even more of a crazed soldier nut, Kurz shows up as a girl crazy "gigolo soldier", and Kaname beats someone down every two pages. Just like the title says: Overload.
Overall I give it a B+ so far.
