やんやんの激闘同窓会

The mascot character of Tenshindo, "Yanyan," is back in the lead role, along with the characters of Marshall Age, Jinn ~Eien no Yuushi~, and Goice, who were selected based on questionnaire postcards!
A fierce battle unfolds between more than 20 characters, including nostalgic characters and characters who have never had an H scene!
The girls have received an invitation to participate in the "Fierce Card Game Battle Royal" by the mysterious Y, and are gathering to fight for the title of "The Queen of Tenshindo".
