I want to watch D. Gray Man Hallow some time next month, so I decided to finally finish the original series first. The plan was I rewatch from 50's up so I remember what was happening before I put it on hold, but it annoyed me not remembering what everyone's motivations for fighting the demons were and now I'm back to watching it from the beginning. It's not as big of a chore as I thought it would be because this show is really good at getting you to care about characters not long after they appear, and I get to see Miranda Lotto's introduction again.
I rewatched 50-75 and then jumped back to 1-5 and will continue forward from that spot.
