Huh, can't believe I missed that. Still, bookmaker might get around that. And again, she'll use these instantly by using AF to blitz him. Unless he has some way around having all his abilities sealed, bloodlusted is still a bit much. If he had some way to instantly kill her the way most other characters with regen that high can, then he'd win no problem. It's the fact that he's so limited offensively that I can't really see him winning this.
In character Medaka is so much weaker than bloodlusted Medaka it's not even funny. Him having regen that high should keep this from being a stomp either way and I think his BFR would work. Since bloodlusted means she uses her strongest skills first, her actions should play out something like this
1. AF to erase him
2. He revives anyway, AF to blitz and use bookmaker
3. During number 2, likely also uses passive skills like Scar Dead to re-open every wound he's ever had, including mental trauma.
If he can prevent or survive all that, he wins.
Again, his only win conditions are plot manipulation and BFR, and they're both slower than her using AF to stab him with a hundred bookmaker screws. Unless he resists power null, in which case she loses hard since that's her only win condition.
There are some people who would argue that she could use AF to negate the act of her being eaten, but from what I remember nobody ever used AF to change their position outside of the normal pseudo teleporting they do, and that requires the movements be possible for the user to do in the first place. Knowing this, being eaten and trapped should be a win condition.
It's also logical to assume his plot manipulation would put her down for good, considering it's only known application on his profile is erasing someone and AF has never been used to come back form erasure. That also most likely bypasses Encounter, as it's not an attack in any sense.
All in all, I'd vote inconclusive, since I'm not certain if he could act before her, and I don't know for sure that Bookmaker and AF in sequence could put down someone with Mid-Godly. If it can she wins, if not there isn't anything else she can really do aside from avoid, but she can't do that forever so eventually she'd get caught. Toss in his time manip and she really has no chance should her first attacks fail.
