Which is the best direction to take this squad

I followed some good peoples advice, took my time and made my akame a beast. I also finally got rid of tsunade as my healer (thank god) most of my level ups will be going straight to unohana until she's 230 but after that I will be free to assemble my team in any way I please, mostly I'm just looking to guidance as to who to build in terms of promotion next, I have 50 specific shop money and 15 of the tickets so I'd have 65 to spend on a character or 2. I have 1 Makoto so I was thinking of buying 2 Makoto from the shop. Was also considering buying 2 Sasuke, or maybe even 2 Kakarots. What do you guys think, what's the smartest move
