第501統合戦闘航空団 ブレイブウィッチーズ ペテルブルグ大戦略

Eila Ilmatar Juutilainen wants one quiet walk through Petersburg with Sanya V. Litvyak, and the base will not give her five uninterrupted minutes. The witches are setting up a New Year's party after the Saturnus Festival, and every attempt Eila makes to ask runs into somebody else's errand. An armored Neuroi turns up over the celebration before she manages it, putting Eila and Sanya in the air alongside Hikari Karibuchi, Sadako Shimohara and Edytha Rossmann.
