A “Non”-Typical Dark Honmaru

"Tsukumogami are a difficult lot to please. Treat one badly and it will fall into darkness; treat it too well and it will still fall into darkness. Disdain it as a mere tool and it will fall into darkness; revere it as a god and it will still fall into darkness. Fall in love with it and it will fall into darkness; have it fall in love with you and it will still fall into darkness." So what exactly is falling into darkness...? Maybe it's the single thread of a true heart left inside a body of steel!
