Rika Aikyou from manga Iinazuke Kyoutei
*Character credit goes to manga author (mangaka) Fukudahda and his work Iinazuke Kyoutei.
As the author has no interest in releasing fanservice related to this work and is long passive in manga industry, this lora model does not hurt his profession.
Either way, if you like this model I urge you to support the original author Fukudahda by buying his released manga work.
