This topic is a bit silly…
If anyone is familiar with the manga/anime Hunter x Hunter, then you will know that they use many unconventional weapons i.e. a fishing rod, playing cards, and even a vacuum.
This got me thinking what if a Go themed fighter was featured in these kind of shows? What kind of weapons and abilities will he have?
Here are my ideas:
Primary/melee item with probably have to be a folding fan.
Go stones will work well as a ranged weapon. It seems like they will make great slingshot ammunition. The black stones have different abilities than the white stones maybe?
And for a special/defensive item, he can use the goban itself. It will make for a great bludgeon and shield. Hard to carry around though (but this is fantasy).
I’m not sure about a special ability, bankai, or power up.
