Isekai Hiroyuki

For a long time, mankind would summon a "hero" from another world once every 100 years to fight the Demon King's army. However, one day, the Demon King came up with a countermeasure against the heroes. The idea was to trap and kill the defenseless heroes immediately after their summoning. To commemorate this historic feat, the Great Demon King designated this year as the "First Year of Trapped Killing". Since then, all the heroes have been killed on spawn by the Demon King's army. In the 1000th Year of Trapped Killing, 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 2channel and a master of argumentation...!
