- Complete the main story missions. As you progress through the main story, you will unlock new characters and rewards, including S rank characters.
- Participate in events. Events are a great way to earn rewards, including S rank characters. Be sure to participate in as many events as you can.
- Summon characters. Summoning is a random process, but there is a chance that you will summon an S rank character. You can increase your chances of summoning an S rank character by using better scrolls and by summoning more often.
- Trade characters. Trading is a great way to get S rank characters without having to summon them yourself. You can trade your characters with other players in the community.
- Use codes. From time to time, the developers of Naruto-Arena will release codes that can be used to redeem S rank characters. Be sure to keep an eye out for these codes and redeem them as soon as possible.
