Dio Drevis

Dio is a twelve-year old boy, roleplayed by The Seventh Sage. He is the son of Alfred and Monika Drevis, and Aya's older brother.

Alfred Drevis
Dio looks up to his father, and despite his gruesome line of work Dio puts time into understanding his father's job. He may idolize Alfred in an unhealthy way, because Aya displays similar traits to their father, yet Dio views Aya's habits as creepy or unnerving, to the point that he avoids her. This consists, despite the fact Aya's experiments involve animals, while Alfred's include living, mostly human beings and are presumably much more bloody,

He may feel he needs to compete with Aya for his father's favor, as evidenced by how he seemed upset when Aya was reading a book Dio didn't completely understand.

Aya Drevis
As stated above, Dio finds Aya creepy and tends to avoid her if he can. However, when he has to be in her company, he is polite enough to her and displays a small degree of concern for her well-being. However, he was envious of her superior knowledge in anatomy.

Monika Drevis
When Monika died, Dio didn't let out many outward signs of misery, opting to bottle it up instead. This implies that he did have a good relationship with Monika, It has also been stated that Dio has become more messy after Monika's death, as she is no longer around to instruct him with grooming.
