I was just serching online for cool Keroro costumes to post, seeing that Halloween is getting closer. I stumble on this picture and thought the girls are kinda cute (mmm~ girl on the left~ =P). I was curious about what “toutou” on their tees stands for so I looked it up (I guess hot chick’s shirt DOES make a good billboard..). Appearently toutou is a pop group consists of 2 girls, Sayaka (L) and Marika (R), and they sing one of the ending theme for Keroro Gunso – Kokoro no Mondai (matters/problem of the heart). I have asked foburro to load it up in the music section so when he does you guys can go listen. Nothing beats good tune and picture of cute girls right? ^_^

This is the cover of the single that they did for Kokoro no Mondai. The girls got “Keronerized”!! You can click to enlarge both of the images.
