Fearing a magic power crisis, the sword and sorcery world of Fairleaf takes to summoning not people, but copies of entire buildings from other worlds. After repeated failures, one day they try summoning not a mere building, but an entire town -- and accidentally get the entire neighborhood of Akihabara, the legendary otaku mecca. After an investigation, Akihabara's culture and technology spreads throughout Fairleaf, sparking a revolution.
