Ultra Jump ships monthly around the 18th-19th. Ch.19 was Sept 18, so Ch.20 falls in that Oct window unless Araki announces a break in the issue notes — he usually flags it a month early.
Don't Google scans — they'll be late and mistranslated. Use VIZ / Manga Plus free tier. Our Ch.19 recap catches you up in 8 minutes.
Is there a hiatus? No announced break as of Sept 28. What time? Manga Plus usually updates ~10am ET release day.
We update this page within 24h of Ultra Jump announcement. Next: full Ch.20 summary on release.
