It's a Sekirei thing! And Minato encounters something else!

"Ah, right, I am so sorry, Minato-sama," Musubi rubbed the back of her neck, her eyes closed with a rather sheepish smile. "It's just that, well, as a Sekirei, I was taught to fight any other Sekirei I came across..."

Uzume chuckled nervously, and waved her off. "Yeah, it's true, we are born to fight, but... Eh, don't worry about it," she chuckled nervously.

"...born to fight?" Minato questioned.

Uzume nodded, and stated, "We're supposed to fight and fight until only one of us is left, as part of the Sekirei Project... The MBI CEO loves to remind us of that, quite too much, in my opinion. But... Eh, don't worry about it."

"...still, it's surprising that Musubi isn't the only Sekirei boarding here," Minato sighed as he started to wash Musubi's back, making her hum in contentment.

"I'm not even the only one," Uzume remarked idly, making Minato pause, and turn to Uzume, eyes wide.

"Eh? There are other Sekirei here too?" he asked, shocked.

Uzume yelped, looking nervous like she had said too much, and covered her mouth, before removing her hand and chuckling sheepishly. "Ah... Never mind that. At any rate, neither I, nor my Ashikabi are interested in fighting in the Sekirei Project. We're more interested in just living our best lives together."

Minato opened his mouth as if to press for more details, before thinking better of it, and closing it again. Uzume clearly wasn't willing to talk more to him about this, so he wouldn't push. He'd just make a mental note to be cautious. "...no more starting fights with other Sekirei Musubi, not even just here," he told her sternly. "Obviously, defending us and others is fine," he concluded as he finished with her back.

Musubi pouted, both at his words, and that her back wasn't being touched by him anymore. "Okay, Minato-sama..." she conceded.

...

Minato sighed as he walked the yard once the bath had concluded, and he had gotten dressed. Miya was still prepping dinner, and he casually strolled about as he waited. "...hey, isn't this the spot where Musubi and I had fallen before?" he mused, walking over to the tree.

He marveled at the fact that he and Musubi had survived essentially dropping out of the sky shortly after their meeting. "...guess this tree acted like a cushion," he mused, reaching to touch the bark.

Suddenly, the image of a young, crying woman superimposed itself into his mind. Her hand was outstretched towards him, and she was silently pleading, "Help me..." Then, as fast as it had happened, the image was gone, and Minato had fallen back on his rear.

"...what... Was that?" he asked in shock.

(Side note, if anyone has an image of an adult Kusano I can use as a reference, please send me the link in messages. Otherwise, I'll just do my best to describe her later.)
