Family Tree (家系図 Kakeizu), originally The Secret of the "SBR Race Complete Record" (『SBRレース全記録』の秘密 "SBR Rēsu Zen Kiroku" no Himitsu) in the UJ release, is the eleventh chapter of JoJolion and the eight hundred fifty-eighth chapter of the JoJo's Bizarre Adventure manga.
A new morning begins at the Higashikata's. Josuke wakes up and goes to prepare himself in the bathroom, in which he meets Hato and Joshu. Starting to grow a stubble, he borrows Joshu's razor and shaves using Soft & Wet's bubbles; Hato and Joshu's faces end up being covered in his hair as a result. Josuke then eats breakfast, during which Norisuke IV is confused to see Josuke not obeying Daiya's orders.
A flashback details the investigation Josuke conducted in the office upstairs. Consulting the Steel Ball Run Complete Record by First Generation Norisuke Higashikata, which is a revised version dating from 1989, Josuke reads about the Steel Ball Run race, its results, but more importantly, reads about the Higashikata family tree. Josuke notices the existence of a minor branch of the Higashikata family which began with the marriage between Johnny Joestar and Rina Higashikata, and ends with Yoshikage Kira and his mother Holy Joestar-Kira. Josuke then tidies up the room and decides to investigate Holy, and more generally the Higashikata family line.
