Oriana's saint killing ability possible

“You should know, Kanzaki owes a debt of grace to me. Think about it, when
she first came to England, who was the one who took care of her? Of course a
fellow Japanese would be suitable. To me, it’s a rather trivial matter. But that
person is rather sensitive about this sort of thing. If she knows that something
like this is happening, she’ll immediately rush over.”
(Cheh…)
Oriana started to make her own calculations.
Seeing Oriana like this, Tsuchimikado seemed to treat her like an idiot, and
continued,
“Oh my. Don’t tell me that you intend to destroy the ‘Tsukebumi Tamazusa’. Let
me tell you, that’s impossible. This thing is like an alarm, once it sends the
signal, it’s over.”
Saying this, Tsuchimikado seemed like he wanted to prove that it wasn’t a hoax,
as he pinched on his own hand-made talisman that he used as a communicator.
“…”
Oriana slightly adjusted her breathing.
Right now, she couldn’t tell whether ‘Kanzaki Kaori’ would come here or not.
Even if that Saint was to arrive, Oriana didn’t think that she’d lose. As long as
she could set up an effective strategy, ready to sacrifice her limbs, she could
probably kill one or two Saints in battle. But this wasn’t appropriate. Compared
to a simple one on one battle, Oriana Thomson had to achieve a higher goal and
not hurt anyone else.
