over the course of time, yes, essentially you can. The span of time it takes you to do so without money is quite long. Depending on how often you get scrolls. Sasuke Susanoo a year or less. I say this because there are many sources for seal scrolls. best thing to do is just stack them for rebates. never pull unless one is active. Itachi on the other hand. I recharge here and there and since his release last December, I only have 41 frags. As an absolute f2p I have no idea. If you've done 800-1200 pulls in kage I guess you could have around 30. But it'll take you a little over a year maybe 2 to get him.

I believe they changed the rates on his frag drops. I dropped around 120 or so and only received 3(pulling them twice). So for those who did take advantage of the edo drop, well played lol.
