Theory regarding the next durante ability (and canto 8 ending)
Seemingly, each of the sapling of light abilities that dante gets when achieving golden bough resonance resonate heavily with the themes and "abilities" of the sephira they are linked to - for example:
During hokma's meltdown in lobotomy corporation - they player loses the ability to pause the game, and the speed of the game gradually increases throughout the day, in library of ruina he is the patron librarian of the floor of religion and has heavy themes of "waiting" and his floor is literally inside a giant clock - his durante ability allows dante to slow down time around them.
Binah was the sephira responsable for the extraction team, who themselves were responsible for extracting ego, and her durante ability allows the usage of ego without using ego resources.
Chesed in lobotomy corporation was responsable for the welfare team - his missions unlocked bullets that heal employees sanity and health - and his abnormality pages in ruina encouraged keeping librarians alive
additionally, all the abilities have been linked to one of the sins - hokma has "pigritia", sloth, binah has "superbia", pride and if we think about chesed in the context of his responsibility to keep employees happy, he will probably have "tristitia", gloom. (plus, he is blue!!)
Thus, I theorise that there will be a part in canto 8 where hong lu is either distorting, or undergoing EGO corrosion (because it turns out his glowy eye is ego of some kind) but then dante says some cool shit like "no, hong lu, you are bound to me - and by me I shall restore you" and BOOM golden bough resonance and we get tristitia and its probably something to the effect of "Restore sinner from corrosion; set sanity to 45 (or 0)"
absolute cinema.
