A special chapter was later published on July 30, 2009.
The first three chapters ("A's to StrikerS") take place in April 0071, immediately after A's epilogue and two weeks before the Coastal Airport 8 fire shown in flashbacks in StrikerS. Additionally, Nanoha's injury in 0068 is referenced in Vita's flashbacks.
Each chapter title is fully styled as "Episode-X 「Title」", except the special chapter 15, which was styled "After Days 「Title」". If the chapter title has a "Phase-X" suffix, it is styled "Episode-X 「Title」 Phase-X". Alternatively, if the chapter corresponds to a particular StrikerS episode, it is styled "Episode-X(StrikerS #N.N) 「Title」".
