Mirja wasn't noticed. Lingering in the not-quite-background was a poor way to get noticed, but she thought it was a really serious situation and her personality didn't really match it, and so she didn't want to annoy the Captain any more than he was already annoyed with her. So, she followed though with her thought and walked over to the 11th barracks, where the men where, as always, fighting each other. With sticks, almost Afraid of the purity of Unarmed Combat. But, she stuck around and watched them smack each other with sticks, until one of them men on there won. And then he saw Mirja, watching with her un-impressed facial expression, and so pointed his wooden sword at her.
"Seems I'm boring you. Why don't you join me on this mat, little girl." He taunted, so she rolled her eyes and stepped into the fighting area, to which the man grinned. "Well, fighting such a pretty Soul Reaper. You have made me a happy man" He continued, which elected a smile from Mirja.
"Well then, next I'll make you a Dead one." Mirja replied, making the man scoff angrily and raise his sword up for a strike. Mirja then rapidly Flash Stepped forward, and slipped under his guard, using her momentum and smashing her palm into his chest around the lung-area, before slipping around to his back, and hitting his other lung with her other palm. She then took a few steps back while the man collapsed into a coughing heap of pain. Her new technique was really going well, and she felt confident to show the Captain so he wouldn't hold scorn for her party-making abilities.

However, far from the intended reaction of 'wow you're so cool, lets all plan a party' reaction she was expecting from the audience, the half-evolved monkeys where glaring at her and brandishing their sticks dangerously.
"So...I'm going to go get rice-cakes" she said, backing away to the door, only to find it blocked by a large 11th monkey. "Errr, gulp?" she offered.
