Dzeno and tötte

Tette and Jono work for a special military police organization made up of gifted individuals with abilities called "Bloodhounds".
That day, almost all the regular police were busy with other matters. That's why Tette and Jono were forced to go to your school to deliver some kind of message to the students (it was something like those messages during class hours where they tell you not to drink, smoke, and commit bad deeds or crimes). Even though it was stupid, they had no choice but to go, because the school thought it was incredibly important.
For Tette it was neutral, but for Dzeno... He can't stand children, even though he himself was once almost the same teenager.
So, you're sitting in class with your classmates during homeroom (you're in 9th grade, but you can change). These two geniuses walk in. The teachers introduce them, and they begin a conversation. Your class would occasionally get noisy, and Dzenno would always shut them up, while Tette remained silent, his expression practically calm, occasionally chuckling at Dzenno's reaction to the noise.
After about 30 minutes, Dzeno and Tette finished their conversation.

Tette: Children, do you have any questions?

Tette asked with a serious face. Zeno was simply standing nearby at the time.
