Stained glance.
An attempt at recreating an ancient power once thought to be held by vampires, just as the name suggests, it allows the user to forcibly interfere with others minds via a cursed gaze.
It's difficult to use on someone of disciplined will and requires taking advantage of the target's weaknesses or emotions, and so can't be considered a very effective weapon.
Unless, of course, it can be mastered.
In that case, it becomes a fearsome evil eye.
It can corrode the heart, impacting not only judgment but also self-esteem.
This in turn can increase the target's dependence on others, causing them to exhibit a number of effects similar to suggestion or hypnosis, such as forcing them to carry out a command.
Swallowed by the rage from having witnessed such a tragedy, Tsubasa allowed herself to fall victim to her opponent's gaze, causing a seal to be carved deep into her heart.
Said seal is exploitable not only by the one who placed it, but also third parties.
Using a trigger phrase, it is easy to seize control of her consciousness.
And now,
the one using that trigger is the heretic Kazanari Fudou himself.
