Third person POV
Later, after dinner, Akihito and Aki are at the dining room doing their homework with Asuka and Niko. Asuka and Niko had just finished washing the dishes with a housemaid. It was a peaceful night, and they are doing their homework communally.
But, the two assassin masters of theirs are struggling with one school subject: World Geography. The reason why is that they focused too much on Math and Physics, thus their geography studies. But, upon seeing that, Asuka stands up and offers to help them. "I'm very at that subject, so I might able to help out."
Akihito and Aki hesitated at first, but eventually gave in since they are desperate and doesn't want to fail in a geography exam.
And so, Asuka began tutoring them in that subject, explaining to them how it works and its answers to the best of his knowledge and ability.
His two masters are a bit stunned to see how to study it.
Asuka admits that World Geography was one of his favorite subjects in school, and that he did a lot of research about it in his free time.
At this point, he, Niko, and their two assassin masters became closer in terms of friendship, not just a mere master-slave relationship.
