Weapon Theory: Ogasawara Nagaharu

As a warrior coming back from the mainland China to participate in the Tenkaichi. There are lots of very culturally rich options that he could use.

If we look at his current attire which is reminiscent of Chinese ming dynasty rider attire. With some martial arts leaning.

So the theory is that he might be using one of three weapons.

Chinese Da Dao- this can fit in with his Shinkage-ryū style and emphasis on winning at any cost and low postures which logically makes this the most likely.

Chinese three section staff- definitely a spicy include and would present a very unique challenge for Ito. But might be just a bit too outlandish for Tenkaichi.

Chinese dual hook-swords- ok so it can catch, strike, and be linked together for extended range and would be another spicy choice for the author to go to, and would be very interesting to see the itosai master deal with another very outlandish martial arts weapon.

I think theres probably even more spicy weapons from the mainland like the chain darts (I didn't include because that's kind of what Fuma was already using) and the Chinese dart spear with the tassel that makes it hard to judge the distant and blurrs the path of the spear tip. (But there's already so many spears already.)

What kind of weapon do you think he will wield?
