It’s useless to make me think that he will do it

Because he will never kill Mashiro; he would rather die himself but I suppose that he will do something so that they will stop trying to kill her. That colonel dude is evil but that spy girl wouldn’t want Yuri to die because she loves him. .Let’s see how this will end, don’t kill him or her! I am not expecting a fluffy ending but not death if you please!
