Oh wait.
That's only if Marisa goes to Yuyuko's place, and we're not sure how exactly a soul goes there once the person has died. More likely she got a one-way trip across the Sanzu River and Shikieiki has sentenced her to hell (as she threatened to do if Marisa didn't clean up her act)... and that's assuming her soul could even pass on because...

Exactly! Everyone does all this cutesy artwork of her and doujins make her act all sweet and crap but a lot of people seem to ignore or are just plain ignorant of the fact that Rin has one of the most evil abilities in the entire series! When she takes someone's corpse their soul becomes trapped, unable to pass on (because the Kasha in mythology could carry off people's souls to hell, even if the person didn't deserve it)!
I'm not sure if this is forever or until Rin releases it, but either way its a freakishly evil ability for someone whose often portrayed as one of the more relatively kind characters in this series!
