Now as for Ways Chronoa can win?
Well let's see DIO's resistances
Transmutation
Disease Manipulation
Mind Manipulation
This is not Good
1. AP Stomp
Literally doesn't need an explanation
2. BFR
Can send him outside of Time from which here is no return for him
3. Time Stop
Remember Demigra's level of Time Stop Resistance thing at the top, well guess what Chronoa can bypass even that level of Time Stop while in base so there is literally no way out for Dio, hell he doesn't have Time Stop Resistance Mentioned at all
4. EE
Chronoa can erase entire timelines. And DIO has no notable resistance to EE let alone 4D Level
5. Causality
Since DIO is from an ALTERNATE timeline, she can just undo the events that lead to his inception and set the timeline back to it's prime state essentially erasing him and with no Acausality to speak of, he doesn't resist
6. Absolute Zero
He has no resistance to cold temperatures much less absolute zero
7. Time Labyrinth Sealing
Effectively Sealing him away outside of Time and Removing all trace of him throughout History
8. DD
Dimensional Domian stamina 1 and given DIO character as a whole HE WILL MOST DEFINETALY TRY TO MOVE and end up getting stunned. From that point she can **** him until his

loses all function
9. Memory Erasure
Just mind wipe, he'll be off guard for a while and then go in for the Kill
10. Summon
Anyone else would make this even more of a stomp
