What changed
- Blue back, white band, red sides. Across the body, the colour now goes blue on the back, then a white band, then red (or orange) on the sides. Before, the blue ran straight into the red.
- The net fades out. The dark scale rims (the reticulation) are full on the blue back and fade out over the white band toward the lateral line, so the red sides are clean. Before, the net ran over the red as well.
- Motoaka, clear fins. The pectoral fins now carry red where they meet the body, a semicircle drawn by the same fin-base mechanism as Showa motoguro. The rest of each fin is clear: the pectoral fins sample the white fin column of the pattern instead of the red side beside them. The tail fin samples that same column, so its red edges are gone. The colour fades to white along the tail root rather than stopping at a line.
- Mizu and Yuki Asagi. A new `asagiForm` gene, rolled after every other gene so older seeds keep theirs, makes 15% of Asagi Mizu Asagi (no red: the band runs into white sides, and no motoaka) and 10% Yuki Asagi (no net, just ordinary scales). Names follow. A Doitsu Asagi is still a Shusui. Rarity is unchanged: all three forms are Uncommon. The sheet tool gains `asagi-mizu` and `asagi-yuki`, and the Koi Designer has an "Asagi form" picker.
Why
A r/Koi judge's three Asagi notes: the reticulation fades out toward the lateral line, with a white band between the blue back and the red sides; the red belongs in a semicircle where each fin meets the body (motoaka), with white fin edges and no red tail edge; and the outcomes include Mizu Asagi (no red) and Yuki Asagi (no reticulation).
