The Japanese version of the Cospa’s Ro-Kyu-Bu quote by a Lolicon that says, ”Mattaku, Shōgakusei wa Saikō Da ze!!” (Truly, Primary School Girls Are Great!!), is now taken down from Animate’s online store.
The quote on the shirt is made in Episode 3 of the sports themed anime Ro-Kyu-Bu, when the hero express his thoughts.
Currently there is also an English version of the shirt, but it’s still available for pre-order from Cospa to be released end of October.
Of cos, this design is not meant to be anything suggestive, but a acclamation of how energetic and determined primary girls are.
