Toshiwasure Guda Guda Order 2016

年忘れぐだぐだオーダー2016

Oda Nobunaga will join the fight for "GUDAGUDA Honnouji" that suddenly appears at Chaldea! This event features an original story written by none other than the one with a super confusing pen name, Keikenti-san! Of course, the scenario was (basically not) supervised by Kinoko Nasu!
