You got it~! Think Iβll go with some world building oriented stuff for this one.
Vampires, like sharks, will occasionally shed their old fangs to make room for new ones. The discarded fangs are a decent magical conduit and can be used quite effectively in the hands of a mage or scientist who knows how to bring out their properties. The quality of magical items created using more modern methods tends to be more stable, which is what Johannes or Iduna would make, and can effectively be wielded by just about anyone with enough training. However, the level of potential power suffers since the focus is on usability rather than specialization.
Items such as Tooruβs Mjolnir, which he passed on to Jun, or the Tsukimitsu familyβs Keys, are more Old World styled magical items that we tend to think of. Theyβre more suited to some mages than others and will almost form something of a βbondβ with the user, enabling them to cast more powerful spells while mitigating the cost of doing so somewhat. These items sometimes even appear to have a life of their own, similar to an Eveβs Lead.
Some eventual projects I can see the Tokyo Branch of C3 implementing, spearheaded (lol) by Mahiruβs group and backed by employees such as Tooru, the Dark Knight Trio, and even Iori himself, are various efforts that actually lend to what C3 claims its purpose is, ie, the peaceful cohabitation between the human populace and the inhuman.
Naturally, the focus is on the vampires lurking within Tokyo. Some of these programs include more mundane things such as a free teeth cleaning with a yearly check in, to more quality of life oriented things where registered subclass are able to receive free packs of blood, which have been generously donated by various C3 employees. Also offered are mental health services, which are kept up to date by keeping a steady record of a Subclassβs living situation prior to death, how their death happened, whether they have living relatives, and also whether or not they prefer to keep their identity or start over.
The main goal of the blood distribution program is to both cut down on the number of unregistered subclass so that itβs easier to accurately tally the number of vampires in the city, as well as discourage fighting over territory or attacking humans. With the main contention of having to take blood to survive taken care of, Subclass will naturally feel less pressure overall. This also curbs the need that, ironically, C3 itself created, to hunt or kidnap mage children to keep as living blood packs so as to avoid having the repeatedly risk discovery through multiple hunting forays.
Ultimately, the hope in putting these and other similar programs in place is to collect enough data that shows a positive correlation between giving support to the vampire populace and situations of vampire on human violence decreasing, thus proving that not only was the Alicein approach to cohabitation one that was executable on a large, metropolitan scale, but that such investments are ultimately a better use of funds than extermination. Once enough data has been collected, Iori plans on putting forth these ideas to other branches with that big ol βwe saved lots of money by doing thisβ as his main point, rather than the humanitarian aspect of it, because he of all people is intimately aware of just how much money talks to rich old bigots lmao.
