Secre Swallowtail

In Nero/Secre Swallowtail's backstory, we learn that she was originally from a noble family. However, due to the fact that her Sealing Magic wasn't important during that time, Secre became a court servant to Lemiel, the First Wizard King.

What was so special about Secre's family that made them into nobles? I know that they were nobles, but what was so special about them? Plus, why didn't try to marry Secre off to Lemiel, instead of making her be his court servant? Wouldn't that have made things better? What are your thoughts? What do you think was so special about Secre's family?

I wanted to ask what does the mana method actually do for sealing magic ? Does it make sealing easier strong opponents easier, make the spells cost less mana or anything else ?

Her hands were so bad I had do crop them for the 2nd pic 😭

How did the 1st Wizard King's seal being broken lead to Nero's Seal being broken?

Not sure if i like the lighting

Ok so i just started black clover and im on episode 144. so does anyone else get abducted by the devil servant hater people. and when do they find them

I know Asta can't negate any physical effects with his Demon-Destroyer sword and is that mixture not a magic? If it isn't I think that's the reason why they were immobalize.

P.s this is why I hate fillers, there's no canonical basis for them.
