You are a hermit who dedicated most of your life to training in the art of the sword. After many years of training, one day you decide to begin a journey to see the world. The air feels crisp as you set out, the scent of pine filling your nostrils. Once your journey has begun, you need money to continue traveling. The city is hiring guards for a private residence, so you decide to take the job. The stone walls of the residence feel cold beneath your hands as you stand watch, the sounds of the city muffled behind you. During your guard shift, you hear a strange noise. Upon arriving at the location of the commotion, you see a man attacking other guards. You prepare to eliminate the intruder. After clashing swords with the chubby man's, you step back, overwhelmed by his unexpected power. "Young lady Kaede, take those breasts, protect them! This guard is not normal, you just run, I'll find a way to escape," he shouts in the direction of the booth where two girls are hidden. Due to your position, you cannot see who is in the booth. You continue attacking the chubby man, trying not to kill him, but his resolution is clear—he is going to sacrifice his life. Intrigued, you question the man. The man stops for a moment. "Breasts, breasts are my motivation. The breasts of that girl you captured are perfect and your companions damaged them. THAT IS UNFORGIVABLE!" Eventually the chubby man begins to collapse on his knees, covered in blood. He notices that you don't seem to understand the situation and are just doing your duty. "You...... you...... you must protect those breasts young man," he says, seeing himself at death's door and recognizing you're not as cruel as the merchant or other guards. "I haven't been strong enough please do it, make a promise from man to man." You are shocked by this man's resolution. As a hermit, you rarely feel such emotion but find yourself moved by his passion. You nod, making the promise to protect those breasts. Leaving the chubby man on the ground after he takes his last breath, you begin to track the girls he entrusted you to protect. The next day while walking through the forest, you react quickly to an attack from a shuriken, blocking it with your sword. The sound echoes through the trees as you prepare for more attackers. The big-breasted girl resumes her ranged attacks until she stops, her chest heaving with exertion. "I will avenge poor Mr. Mie's death," she says, positioning herself and taking out her sword. "He may have been a pervert but he didn't deserve to be killed like that." Manyuu Chifusa tries to kill you by attacking mercilessly, using her chest techniques to confuse you, but none of her attacks work against your disciplined defense. "Chifusa-sama!" Kaede shouts, beginning to attack with shurikens to distract you while you fight. Eventually the fight is decided when Chifusa loses concentration due to exhaustion, retreating to Kaede as her last position. When you see that they stop attacking, you decide it is a good time to talk, knowing from your training that fighting and talking simultaneously is inefficient. You approach the girls to start explaining.
