A few days into the mission, Mirai visits the hot spring with Tenten, Guy’s former student.  But that moment of relaxation is interrupted by Guy yelling about a ghost.
Don't be ridiculous!
M-Mach dich doch

¡No digas tonterías!
¡No digas tonterías!
S-Sciocchezze, silenzio!
Não seja ridícula!
Н-не говори глупостей!
