A/N: Now time to get on with the stories.


While they were talking a letter suddenly dropped in front of them.

-

What goes up while it goes down?

Can it cause a horrible death?

From high above you see,

Loose hinges may be guilty.

-

"We need to find out what goes up while it goes down?" Ruka said.

"Goes up while it goes down—from high above," Natsume mumbled, "Oh jeez." Natsume quickly ran back into the building where they had the classes. He ran to the top floor while the others managed to catch up.

"What's wrong?" Ruka said.

"Stairs goes up while it goes down and horrible death could mean he loosened a screw in the top staircase and if someone steps on a loose step. The person could fall," Natsume said while checking the steps. Then he finally found the loose step and fixed it.

"That was close," Mikan said.

"This guy is really pissing me off," Natsume said. He looked at all the letters and studied them. There was another letter on the staircase. Natsume grabbed it and opened it.

-

Watch your breath?

It could be your last,

Like toxic airs in the room with many boys,

Or even a more than that.

-

"What does that mean?" Ruka said.

"Damn, there's probably some toxic chemicals in the air vents in the boys' dormitory. Something dangerous to breathe it," Natusme said.

They ran to the boys dorm and searched the air vents. Finally, Ruka found it and they managed to get rid of it.
