I will edit Kev's profile later.
Magic: This is nothing new for Kevin, he already absorp magic from magical beings. I'm pretty sure that he can absorp Sepht magic.
Stop: is mood, seeing that Kevin can also stop time, and slow time around everything to speed himself up.
Break: I don't know if Kevin could tank it though.
Reflect: If only work on magic then it pretty much screw.
Wall: seems like just stats-amp technique, no to mention that thanks to Gil, SBA says that time and date are chosen in such a fashion that their characters are in theirs strongest, and seeing Kevin power increase in pure darkness...
Silence: Useless, someone wanna argue that Kevin need to speak for using his powers, this techinque is useless.
Toad: Kevin can mutate himself as his whim, this will only delay him for a bit until he morph himself again.
Final Attack: Well, if it fail to kill Kevin, then Sepht is screw again.
Arise: I doubt that there's other guy there to be resurrected.
Death Sentence: Again, he could slow time to delay it, but he will die in the end.
Haste: Kevin can counter this with his own time manipulation.
Slow: Same as above.
Magic Breath: Does this can be counter with elemental resistance?
Pandora Box: Again, I don't know if he could tank it.
Death Force: This literally says "nope" to Kevin's time ray.
Death: how does this even works?
Meteor: Depends if the meteor will come before the battles ends, which is really unlikely.
Willpower: Kevin says bye to possesion.
Energy Blades: everyone who is above room level can easily rip, tear or cut steel like nothing. And Kevin can easily swallow this.
Octoslash: Ever heard of a good punch?
Telekinesis: He has telekinesis too.
Telepotation: Again, how does his teleportation works?
Hearthless angel: gameplay mechanics.
As for now, I say this is a inconclusive, both can counter each other abilities. 5/5.
