Biwa Hayahide (Christmas) has strong Turf aptitude and is best used in Medium to Long-distance races, with Pace Chaser as her primary running style. Biwa's growth rates are 12% Stamina, 12% Power, and 6% Wit, making her well-suited for different builds.
Biwa's skill kit centers on Pace Chaser-focused abilities, including positioning and straight bonuses that help her maintain a good place near the front of the pack throughout the race. These skills support consistent mid-race control, allowing her to meet her activation conditions reliably.
Her unique skill activates in the mid-to-late phase of the race if she stays within the front half of the field early and remains near the lead later on, granting a velocity boost. This condition aligns cleanly with Pace Chaser builds and is unreliable in Late Surger or End Closer setups.

| Medium | 1200 | 900 | 700 | 450 | 450 |
| Long | 1200 | 1200 | 600 | 450 | 350 |
For Medium. 1200 Speed, 900 Stamina, and 700 Power are enough. These stats ensure Biwa Hayahide (Christmas) is stable through the race while maintaining enough strength to contest the final stretch. 450 Guts provides added stability, and 450 Wit is sufficient to support consistent positioning and skill activation.
In Long. Try to be close to at least 1200 Speed and 1200 Stamina, with 600 Power to maintain positioning through extended stamina checks. 450 Guts remains adequate, while 350 Wit is enough since Long-distance races emphasize endurance and sustained pacing over frequent skill triggers.

Training Strategy
Junior Year
Biwa's first career objective starts with the 1600m Mile Make Debut, then the Asahi Hai Futurity Stakes (1600m). Focus almost entirely on Speed to clear early objectives smoothly. Add small amounts of Wit when convenient for positioning stability, but avoid Stamina training at this stage. Use this period to raise Support Card bonds and capitalize on early high-value trainings.
Classic Year
Objectives quickly transition from Medium to Long distances with Satsuki Sho (2000m), Tokyo Yushun (2400m), and Kikuka Sho (3000m). Begin incorporating Stamina training early, aiming for about 400 Stamina before Tokyo Yushun and 500+ before Kikuka Sho. Continue developing Speed alongside Stamina, and start securing Pace Chaser skills and at least one recovery skill to stabilize long-distance clears.
Senior Year
Senior Year is defined by repeated endurance checks, including Tenno Sho (Spring, 3200m) and the final Arima Kinen (2500m) win condition. Stamina takes priority here, with Speed largely established already. Remaining turns should be used to adjust Power, Guts, and Wit, finish key skills, and manage condition carefully to avoid setbacks before the URA Finale.
