You're right. Category 5 is usually the highest level, but since she's a demigod she might be a category 6.
Here's the yandere classification levels.

Category 1: Threatens anyone of the opposite sex who approaches the target of their affection. Will not actually use violence unless "cheated on." Can be reasoned with.

Category 2: Will not hesitate to use violence on anyone of the opposite sex who gets too close to the target of their affection. Can be very dangerous to the person they love. Very hard to reason with.

Category 3: Nobody is safe if they get too close to the person they claim to love. They will even kill their lover's family because they want all of their lover's attention for themselves.

Category 4: Is willing and able to kill an entire country if they feel those people looked at their loved one the wrong way. Extremely dangerous. Showing affection or even mild kindness to anyone other than the yandere can lead to chaos.

Category 5:They appear to be able to bend the rules of reality and will manipulate the entire world to benefit their loved one. Will not hesitate to kill the whole planet if they're enraged.

Category 6: You fool you've gotten the attention of a crazed deity!!! WE'RE ALL FUCKED REALITY IS FUCKED!!!

I knew it the instant I saw her eyes. She's one of those category 5 yanderes... This will be a very tricky situation.

Goddamn he split the sky!!!! It's time for a new era for the Baskervilles. I'm eager to see what the next arc is.

That was a short break!

Seol is monstrously strong and monstrously cute! I hope grandpa's body reformation goes well!

I see that low key coffin dance meme! Poor girl. She got did dirty.

I have a weakness for elves my self preservation gets dropkicked out a window when it comes to them.
Would wood.

His Li'l bro living his best normie life.
He's not jealous at all lol.

That's some absurd strength! That swing looked like it would crush 5 regular humans and he just stopped it barehanded with 0 effort. Dragon Supremacy indeed!

To be honest I still don't remember who he is, but if the MC chopped off one of limbs he likely had it coming.

Legally ambiguous Raichu joins the fight!

This one is a bit different. Not bad at all. Very gritty.

R.I.P Count Zelot. RIP AND TEAR!!!!

Fucking around phase was completed. Finding out phase has now begun.

At night, with an aerial attack advantage, and with full invisibility. Forget that shit. This was lost before it started.

Wow this is a great one! Eagerly awaiting the next chapter.

Hell yeah I'm crying!!! This shit is beautiful!!!

Yeah but Ares is a massive prick though. We all know he had it coming.

No kind of self preservation instincts huh?

Goddamn it!!! Like moths to a flame...
