A hundred years, no need to go that far.In the last chapter, it was implied Dorothy might have been dead because of all of the time that has passed (a thousand year or something like that) since she disappeared, but since she's an Elf that's not a problem. Yatta I guess.
might not be a coincidence, it was dorothys old house that got turned into a dungeon, her then being asigned to the area could have been plannedIt feels too convenient they'd find Dorothy without even lifting a finger, apart from saving her from the embrace of a man-eater plant. But then again, I'm not sure how it could be handled otherwise, anyway. It's not like Hajime & Lily would start travelling all over the world to track her down. If it was the original Dorothy's granddaughter, then maybe this would feel less convenient.
He actually reminds me more of the Millennium Earl from D. Gray Man. Polite, insane, and hella evil. "Konban Wa Stubbled Boy <3" even had the whole nicknaming with hearts crap down to a T.The Dungeon Wizard reminds me of Magic Man from Adventure Time, crazy guy with too much magic who annoys the main characters then disappears.
