Instruction: Hakurei Shrine Maiden's Training Schedule

A Spell Card of Yukari Yakumo from the world shrouded in scarlet mist (a Touhou LW original). She recalls the days when she trained Reimu. There's no decisive information about how the Hakurei shrine maiden and the Youkai Sage met or how they spent their time together before the never-ending winter incident. Restricting yourself only to trustworthy sources, you could even conclude that before the incident, the two didn't know each other. But examining important documents like the Gensokyo Chronicle and the Gensokyo Record, you can't help but recognize how far their strong connection dates back.
