I know it was a Sword Art Online spin-off.
- There was Asuna and Silica in their SAO avatars.
- They meet a "Kirito".
- That "Kirito" turns out to be a female player.(like reverse of Kirito's GGO avatar)
- She is a fan of Kirito
- I think it takes place inside Aincrad in ALO and before Kirito transfer his ID to ALO again.
Anyone know the title of this spin-off?
