-- Ouch. -- A fist slammed into Gai's cheek. He was ready for the blow, but it was strong, ringing in his ears. He staggered. -- Good. I have a feeling we'll have plenty of trouble ahead, but you can be a commander. You have a strong hand, but that's not even the most important thing. I'll explain now.
The man sat down against the dilapidated wall, crossing his legs.
-- Listen carefully. I don't remember (the irony!), how many years I've been earning my living with a sword, but there are some principles that are important, and that you probably don't know yet. The first principle is that a subordinate must trust the commander. Preferably, they should also respect him. But if a subordinate doesn't believe that the commander knows what he's doing, they won't obey. You can try to force them with fear. But the commander is one, and there are many subordinates. They quickly stop being afraid. Fear must turn into respect. Otherwise, it will turn into hatred. To trust someone, you have to know them. That's why I interrogated you. The second principle is that there is usually only one moment to make a decision in battle. If the commander hesitates for too long, it's even worse than if he makes a mistake. Therefore, when it's time to strike, you have to strike, not think. The third principle is that there are many people in the squad, and each has their own opinion. So you have to adapt to that. And believe me, I'm far from the most problematic person you'll encounter. I've already explained the fourth principle. If you don't handle it, we'll all die. Remember that.
Gai sighed and scratched his bruised cheek.
-- Well. You've got what it takes, so to speak. You also know how to fight. Everything else is a matter of our luck. You can interrogate me now.
