For context, Hojo Yoshitoki (1163-1223) who was a second shikken (shogunal regent) after Tokimasa is a direct few times great grandpa of Tokiyuki who belongs to tokusō line (the "royal"/main line (there were several branch offs)) of Hojo family.
Yoshitoki is a main character of amazing Japanese historical taiga drama Kamakura-dono no Jūsan-nin aka "13 lords of the Kamakura-dono" but outside of Japan simply "13 lords of the Shogun", played by Shun Oguri

Highly recommend watching it, great plot, well written characters, amazing soundtrack (composer is Evan Calls, the same guy behind Violet Evergarden and Frieren musical accompaniment), nice historical authenticity and may educate on how late Heian era-early Kamakura era Japan worked and looked like (however would still recommend having a basic knowledge of Japanese history specifically around this time period because those who are not ready may still be confused. Buyuuden Japanese History on YouTube would be great for starters before diving into the show). Only downside of 13 lords of Kamakura-dono for some people would be that is quite long... each episode is 45 minutes and there are 48 of them although first and last episodes are more than an hour, this however would actually be a plus for others ¯\_(ツ)_/¯
