Allandra and Ignis have lived for the past two years at Rokkaku, a secret training school for ninjas. And now they've been assigned a secret mission in London - which will bring them across the path of their drug-baron father. A surprise visit from Michael, their brother, convinces Allandra that he's changed, but Ignis has his doubts. So when Michael turns up at Rokkaku, looking for a family reunion, Ignis is even more suspicious, because he is unsure if Michael is still working for their father or not. Allandra is now very confused and by welcoming Michael to Rokkaku she may very well be bringing danger right into the heart of the ninja school...
