Technically first video game Vietnamese Heroic spirit, Lo Lei (as a megene girl) was in a gag 4koma and is also a Vietnamese hero.
Yeah knew about it, the thing is that Le Loi was basically a fanservant that got included in Fate/school life manga thru a drawing contest and then got animated in Himuro Universe OVA, so their canonity is a bit on the fence. Here "Trung Sisters" is officially designed for the game
