I love the Shirogane's Dad. He had like, 3 pages, and he totally owned them.
Also, god the tsundere is strong with this sister. And seriously, it hurt to see how mean she can be to her dad and her brother because of that. I'm really not fond of this kind of things. Really, I can understand the "my dad is annoying" stuff, but it's not like the Prez is acting in a bad way with her, she could show a little more visible appreciation...
