'Wen Wu Shuang Quan' . . Tough guy, eh?
Just for the benefit of others who may not get it, it means:-
Wen = literacy / book-learning / scholastic aptitude, abilities;
Wu = martial / martial ability;
Shuang = twinning / both / a pair of / equally in amount;
Quan = having it all / complete.
So Tashigae's signature means -- 'Having (in equal measure) both scholastic & martial abilities'
-- in other words, a VTG
I'll rather be happy than right, anytime.
