What BS is this? There is no way they are evenly matched. Sure their bravery stat is the same but flappy earlobe guy is inferior in every other stat.
Same is true for aptitudes. Both have Calvary, Infantry, and Archery at S, but where dipshit has Bs and Cs for Weaponry, Fortifications and Strategy, Ritsu is all As and Ss.
So the tl:dr is that while Dan and Ritsu are evenly matched in Bravery and Infantry Aptitudes, Ritsu is utterly dominant in Wisdom, Strategy, Weapons and using the environment to his advantage.
