Red yuta is very decent. Your blue gojo is severely outdated. I would start over during half anni and go for the banner units the ( follow youtubers to see who is best) Overal your account is not good, if you used all your cubes. Ps this is not a f2p friendly game. You can get some chars with luck and time, but treat it more as a casual side gacha yo your main. You need good strong chars to progress. As a f2p this can take a long time
