Yeeeeeah Oden seems dope so far. Kinda has a delinquent vibe as well. Given that he and that Asha'rah dude were only shown in silhouette, we're still due for a full on flashback.
There's a fith retainer seen with the other four samurai in the past that wasn't sent to the future with them. I wonder if that's a character we've seen before?
Speaking of the time-time fruit, it looks like it can only go forward in time so thankfully no crazy time shenanigans, but still...it's a pretty powerful ability. If Momonosuke's mom is truly dead, then hopefully that fruit hasn't fallen into the wrong hands.
But yeah I'm hyped to see Onigashima Island. Shit's gonna get crazy.
