Visitor

Klein and Leonard lifted their gaze from the letter and exchanged glances. They muttered, "He's crazy, right?"

"Lanevus is secretly a lunatic?"

A lunatic who truly has a delusional disorder and an antisocial personality… Klein thought and felt a tug at his heartstrings. He quickly redirected his gaze to the letter.

"Ladies and gentlemen, the hint is that I've placed a bomb in Tingen, a bomb that will grow stronger over time.

"Seek it and finish it before it explodes. If you lose the game, there will be a boom, and the entire city of Tingen will be reduced to a ruin. Trust me, I'm not lying at all about this.

"—Lanevus, who enjoys giving his friends pleasant surprises."

"A bomb?" Klein looked at Leonard and muttered to himself, perplexed.

Leonard held the letter up to the sunlight and looked as he flipped it around. He didn't find any other clues.
