Kayo Senju — memorable quote from Black Bullet

“Wiping out any and all injuries as if they never happened. A spell like that... Do you really believe he can cast it without paying any price? In order to rewind the Eidos changelog and make a full copy,the stored information must be read in its entirely. Needless to say, that includes the pain and suffering experienced by the injured party. Not only that, but it's transmitted instantaneously in condensed form. For example, from the time that Isori was injured until brother cast his spell, roughly 30 seconds had gone by. Whereas the time Brother spent reading the Eidos changelog... was approximately 0.2 seconds. In that blink of an eye, my Brother's mind felt 150 times the pain and suffering experienced by Isori, condensed. Everytime Brother heals someone's wounds, that is the price he pays. Do you really mean to say that he should still use that power for others?”

“Justice isn’t something that you can just proclaim. It’s a feeling you should keep near your heart.”

“I want you to please understand the scales of my heart will always be swaying back and forth. But there is something you should know. I will never lean to one side or the other due to the weight of gold coins.”

“You're not a strong person, so you can really understand how weak people feel. I mean... Most humans are weak, including me... But if I got an order from someone who saw things like I do, no matter how tough it was, I'd do my damnedest to carry it out.”

“There are times we can't run away, no matter how bad the odds are. When the people we're supposed to protect are threatened, we have to enter the fray and shield them. And it doesn't matter who or what the enemy is. We need to master skills and get stronger, with artillery as well as hand-do-hand combat. I think that's our responsibility as strong soldiers.”
