The Invasion of '83

The Invasion of '83 (１９８３年の侵略) was a major incident that occurred on Halloween of 1983. Having been told by Mecha Mima that Konata Izumi is Manhole's enemy, his goal was to find and murder Kanata Izumi, Konata's mother, with the Super Mecha Death Drill. He successfully did so while stopping others from calling police by using his hackers. When he got inside the Izumi Clan's home, he attempted to murder Soujirou and Konata, but one of Soujirou's spell cards rebounded and hit Manhole instead, causing part of his soul to be torn out of his body, and accidentally making Konata into a horcrux.
