Nemechi is a mechanic in the Nintendo 3DS version of Devil Summoner: Soul Hackers. It is used to summon demons by spending D-Souls, which can earned through Streetpass or exchanging Play Coins for them. The demons accessible through Nemechi were not available in the original Sega Saturn version of Devil Summoner: Soul Hackers, either being entirely new or using alternate designs from previous Megami Tensei franchise games.
