We spent a few more minutes talking about the Demon. From the intel that Tina gathered while running around Los Angeles, San Diego, and Las Vegas, she managed to reduce the possibility of the Demon's base to two.
'B-Rank Metal Gnoll Dungeon in Los Angeles or C-Rank Mermen Dungeon in San Diego, huh?'
The second arc, the Demon re-appearance, was set in San Diego. Another party raided the Demon's base when the Demon was out of it because the Demon was dealing with the Fake Artifacts thing.
The Demon was furious when he found that Awakeners raided his base, and that was the beginning of the second arc.
However, from what Tina said, something strange didn't add up to the story I remembered.
'The Demon's appearance that she saw in the Prison is different from the one that I described in the novel.'
