It's an impressive giveaway, but it should be pointed out that FGs on DMM don't have the same value as Nutaku: an 11-pull on DMM is 5000 FGs vs. 50 on Nutaku.

Not to detract in any way from the point though; it's pretty generous (the newest 6* girl is the one given for free along with a 6* ticket), but don't think you're going to do 11-pulls all day.
