A Certain Scientific Railgun in English so far
The English edition started with Vol. 1 on Jun 7, 2011 from Seven Seas. In the 14.8 years since, 20 volumes have come out — one about every 9 months on average. The pace has slowed lately: recent volumes have come out about every 1.1 years. Our predicted dates follow this slower pace. The longest wait was 1.6 years, between Vol. 16 and Vol. 17.
Japan is at Vol. 21 (Oct 27, 2026), so 1 volume is already out in Japan but not yet in English. At the current English pace, releasing it would take about 1.1 years.
