Tokiomi Tohsaka considered himself a lucky man.
Although he was on the verge of dying from illness, he could leave behind two wonderful daughters, a good adopted son, and a good student for the Tohsaka family.
Rin could inherit the Tohsaka family's magecraft, Sakura could inherit the Matou family's magecraft, and his student could maintain the generations-long relationship between the Church and the Tohsaka family. As for his adopted son, he could take his place in the Holy Grail War and bring the Grail back to the Tohsakas.
His only real regret was that he wouldn't live to see any of it happen.
“Father, it's time to take your medicine.”
Tokiomi Tohsaka accepted the bowl of medicine his adopted son handed him, feeling rather wistful.
“You really are a dutiful son, Dio.”
