Five Times Shiro couldn't be knocked off balance, one time he was, and one time he trusted the team to see. Or, when sibling bonding goes wrong. (Standalone story: You do NOT need to read the previous in the 'series' for this)

Having grown up in Japan, Shiro was used to the anti-ghoul propaganda and the strict lives they had to live through. So, when he moved over to the US to join the Galaxy Garrison, he was very much surprised over the fact that ghouls had actual, proper rights that let them work for the government and go to space. However, being sent on a mission to space with two mature ghouls and supplies for them was much, much different than being in charge of four teenage ghouls while fighting a galactic empire and having to make do with the supplies that they had on hand. AKA, Shiro is the only one in the castle-ship who is completely human, and is completely done with no extra fucks to give by the end of it.
