#arkus

MC's father, Arkus, would hunt down the person/thing responsible for their death. If it was sickness or something else in that vein the physician who treated the MC would take the brunt of that.

Alessia, the MC's mother would throw herself into her work. To most it would look like she didn't even have a grieving period, and to an extent it'd be true. Mentioning the MC in court while she's present would turn into social suicide, she wouldn't want any reminders of their death.

Karus and MC's sibling would never be able to act like they've gotten over the MC's death.

Karus would blame himself and likely spiral into a whole slew of bad habits. But only after helping his brother in law find the responsible party.
