Just like berserkfury said, for Hime Dol to be so low while not being ranked yet is a really bad sad for the series. It happened to Hungry Joker and to Mutou Black too.
Also it's the only series in bottom 5 that is in "relative" danger. Kochikame has been ongoing for more than 1800 chapters so Jump will not cancel it (most likely), Nisekoi will have its anime air in Winter, I think so no chance it'll go. Galaxy Patrolman Jaco will end in a few weeks and Bleach being in its last arc the editors will probably let it end on its own.
I thought Kochikame was unranked anyway? Much like Jaguar used to be?
Kochikame is probably ranked but it will never be cancelled. So its place is of no importance.
