We Tried Having a Group Blind Date, but It was an All Stars Affair and a World Crisis (合コンやってみました。 ただしオールスターで世界の危機ではあるけども。?) is a short crossover story written by Kamachi Kazuma on his personal website.[1][2]


Story is about the characters getting into a group blind date once again in Jinnai Shinobu's house. Touma watches over Index, Mamoru tries to trick everyone so he wouldn't need to be partnered up with Bunny Girl Karen, and Kyousuke gets coccooned up by the White Queen. After Mamoru's failures, Touma ends up being the target of the girls' ire as they want to end up with their own partners and want to eliminate him but ends up disturbing the White Queen's cocoon with Kyousuke, causing the end of the world.
