Worst wishing system ever. The characters are free but you have to get their attacks by wishing amongst so many characters. After playing for quite some time, I could only get the Ultimate Jutsu for only two characters, which means I didn't have even 4 characters who have all attack moves in a party of 4. 🤦🏻‍♂️ The drops are random and resources early game are scarce. Would not recommend!
