A week sounds good. That way the RP doesn't COMPLETELY grind to a halt, but there's still time to keep things going. Lord knows I'm NOTORIOUSLY bad for keeping up on tags. Likewise, I fully believe in players deciding how a log "turns out" between themselves OOCly.
As far as what I would like to do? Currently? The Remimuse is scouting out her new land and nommin' some peepz. Sakuya may just be put on a bus or retconned, because Remi seems to be... ohgod... interested in Arsenal "protecting" her.
