[Based on their armor, swords and the aura they emit while patrolling, you can tell that these samurai are far more formidable than those you saw at the entrance of the residence. They are the elite force of the Otani family's eldest son.]
[You come to the entrance of the vast sleeping quarters where the unconscious old family master lies.]

[You yell at them, but they remain as they are. Although you haven't turned your back around, you sense many samurai rushing towards this location.]
[Would you force your way into the sleeping quarters, or would you retreat for now?]

This is not a good place to storm. The best strategy is to win through smart means.
