Review Detail of OttoBOT in HACKING SYSTEM

You must stop doing this. I mean the story to fast paced isn't? He got a hacking system (although he wasn't used it to hacking something, but to bought a magic, is it a fantasy store system or hacking system?) And get revenge to an unknown man, after that he goes to FT world and suddenly got Acnologia's dragon slayer magic? i hope you can make an improvement soon...
