Haku is male and the team composition differs from main to main but in most cases Iruka and TenTen great ninja war are included with TonTon.
For fire main you want Anko for the barrier, for water and blitz you want Darui and for wind Gaara.

They want you to think Haku's male, but in reality Haku's a trap lel. Also thanks for the tips

The current best team available for Azure Fang for World boss is this one (or at least is the one that grants to me the best outcome):

Azure Fang Haku x

Bee SST Utakata x

talents: 41413, summon: tonton.

bee mystery on haku in round 1 and 3, haku mystery in round 3 after main used her standard attack and all the chases are delivered.

the haku i talk about is not edo tensei haku but the normal version of him because is 5 star, gives you a boost also in round 4 and his standard attack hits way harder.

The damage delivered is around 20% higher than the tenten gnw, iruka, wb asuma lineup that beats the haku, iruka, tenten gnw one by around 10%.
