The first ally event which is unlocked after you've finished the qualifying round of B rank tournament. To begin it, go East from the B Rank Tournament Reception to run into the cave. Run along the tunnel until you reach a duo of ninjas - Ohnoki and Mu. Start the conversation after which - what should already be obvious - you will have to defeat them.
This encounter, just like the whole B rank tournament, is slightly more difficult than the previous ones - the enemy will block more, use dodges and regularly his substitutions. Additionally, the enemy specializes in long-ranged combat - he will be trying to gain as much of breathing space as possible. Without a doubt, his ally, Ohnoki, will help him with that - he will regularly shower you with rain of rocks. The best solution, like against every long-ranged character is to stick to the enemy - if you manage to do so, the whole encounter is very easy.
After the fight you will have a short conversation, after which the event will be finished. For completing it you will receive:
- 3000 ryo
- 2x Paper Bomb - Strong
- Ninja World Tournament allies: Ohnoki, Mu.
