I've been playing around with a Nisei Division: The Next Generation deck since Intervention was released, and I think Fumiko Yamamori (along with Hyoubu Research Facility) really makes it sing.
Fumiko stops runners blindly allowing you to fire the first subroutine on Aiki and gives Marcus Batty and Caprice Nisei plenty of extra bite.
Rezzing this and Hyoubu during a run can really twist things in your favour. Playing as Nisei with this combo, the best possible outcome of winning a Caprice psi game delivers a 2 credit drain for your opponent, 1 credit gain for you, 1 meat damage and an ETR. Not too shabby!
I can't imagine this will see any play out of faction, but it could find a home in plenty of Jinteki decks. It won't win you a game outright, but it's definitely an extra headache for your opponent.
No-one was asking for a boost for Nisei, but I'm glad they've given us one!
