Now to be perfectly honest, while the story is typical Shounen trite; the fact that the organization has branches all over the globe means that there's good opportunities for all sorts of supernatural shenanigans and fun times with local legends.

Now, unlike the manga's protagonist and his friends; the escalation of power and introduction of crazy abilities will be much more reasonable and lower key due to the fact that the setting will not involve any major movers and shakers in the verse from the very start of this RP, mostly small-time and organized criminals along with the occasional rogue magic app user/low-level immortal. 

Given my distaste of the source manga, expect things to go utterly crazy and/or brutal whenever canon characters are involved.
