NO, THIS IS NOT REFERING TO FUUIN NO TSURUGI.

I was thinking...
'Ken' is the 'On' reading for the kana used. However,
'Yari' is the 'Kun' reading for spear, and others are also 'Kun' readings instead of 'On'...

Shouldn't they all use the same reading...?

Which are the correct readings for the weapon kanjis?
Currently I am using
Ken
Yari
Ono
Yumi
Tsue

Well, technically they're all correct readings, but you know what I mean... which ones are supposed to be used?

the japanese reading for sword is 'tsurugi'
they use that in FE3.
Ken is more widley used though, so just stick with that.
