Akio clenched his jaw tightly. It was just like Joaquim to rub salt in the wound, especially on one that affected his dignity. He thought about responding to Joaquim's lines, but decided it would only dig the pit deeper. So he just sighed deeply instead, as he heard Amaya's reply to Akemi and an angry Satoru. "I was making a bomb. However, it is harmless towards other than people, so please don't fear I would ruin the house. It only makes a loud sound and a bright flash"
As Akio saw Amaya pulling out shards of...something, possibly metal out of her skin, Akio felt his own skin crawl. "I apologize for not waiting, but if I don't pull them out, it could kill me, I'm afraid these things are slightly poisonous, it wasn't planned as I didn't get what I wanted when I was buying the parts." That wasn't good, "Hopefully she'll be fine." Akio thought.
He then heard Akemi's reply to his earlier question, "Keira-sama, your sister, is hurt. Please, tend to her wounds as I have only stopped the bleeding temporarily."
"Smart girl," Akio thought. "the idea is not with faults though, since I'm no doctor." Akio sighed. "Nevertheless, I should still offer her my thanks..." Akio began to follow Akemi, and as he passed Satoru, he quietly spoke. "Satoru, please make sure that everyone returns to their quarters," Akio caught a glance at Joaquim's sitting figure inside of Amaya's room. "including him, then please return, I will return shortly myself." After he finished speaking, Akio continued to follow Akemi towards his "injured" sister.
