You can play as position 1 azure that spams shark bomb + experimentation. Have Hinata in front also to protect you in round 1 (always use her shield). Use Sasuke (skillbroken if possible).

Talents: 2 - 2 - 3 - 3
Summon: Small/Giant Katsuyu

:: Try to boost your main's initiative so she can cast shark bomb first round 2. Be careful with fire main/kurenai users or anyone with debuff mirror. If soon you get GNW Hinata, then that would do much better. Good luck fellow f2p. I wish you well in your journey, no matter how rough the road gets.
