Running toward her directly is cool and fun, but if he know for example that they intend to kill her by making a huge explosion or by just sending assassins or by using a traitor in her ranks, it'll help him greatly to protect her.
Can't believe that the strongest entity in this manga doesn't know what assassination means(unless you know,assassinate has some kind of hidden meaning in this world ,"torture/rape" is prob the words im looking for)
P.S. if my prediction is correct then my vanillaass can't handle it
