So, I really like how your voice sounds but you could redo these and put more emphasis on the emotional queues at the end of each line? Itsuki is a very open person with his emotions, especially in the manga. He literally 'jumps for joy' accidentally when he finds out the lord of the land needs to be punished. He loudly and emphatically denies the accusations posed by the group. He's been called out and it flusters him.
