RO 500 is a virtual character from Kancolle browser game which popularity soar all over Japan and has since animated into anime and manga.
Kancolle ( Kantai Collection ) is a Japanese game where military assets animated as anime girls and battle with others.
RO 500 here is a second class submarine Type IXC Submarine.
Can’t tell you guys much about her other than what’s written in Wiki since I tried reading their 4-koma manga once, was bored to hell so I decided not to watch its anime.
RO here is made by Laham. All the kancolle papercraft we posted before were made by Laham and apparently RO is a paid model where you can buy for 500 yen.
There are other paid model by him , check it out as there are all worth the price.
