Isekai Hiroyuki

Synopsis

For a long time, mankind would summons a "hero" from another world once every 100 years to fight the Demon Lord's army. However, one day, the Demon Lord came up with a countermeasure against the heroes. The idea was to trap and kill the defenseless heroes immediately after the summoning. To commemorate this historic feat, the Great Demon Lord designated this year as "the first year of the trapped kill." Since then, all the heroes have been killed on spawn by the Demon Lord's army. In the 1,000th year of the trapped kill, the summoner was very worried. "What kind of brave man should I call? I don't know...someone make my worries go away!" The summoned hero turned out to be Hiroyuki, the founder of 2chan and a master of argumentation...!
