Author's Notes:A story where what if a single change happened that cause the story to not be about Asta but instead follow Secre Swallowtail/Nero instead. Though it seem like a minor change this had various changes to the world of Black Clover. Like Julius never becoming the 28th Wizard King, Mimosa being in the Black Bulls, Noelle being a Silver Eagle, and Asta never joining the Black Bulls

Secre Swallowtail could not believe that this was happening as to how could they use the tools that she and the prince worked on in that fashion. They were taking something meant to help others and use it to cause harm to them as well.

'Hopefully, this does not set up a trend where others try to weaponize their tools for harming others merely for their own self gain' she thought.

She went about collecting the magic stones that had been left behind after the Elf massacre. Though she was shocked to find that the demon was gone all of sudden as quickly as it appeared it had seemingly vanished without a trace at all.

The devil that was the mastermind behind everything was shocked at the sight before him as he not only failed to get a body and a grimoire the city had only be attacked for just briefest of seconds by the demon Litcht turned himself into. Leave just enough to know who and what attacked them.

Scere was not going to letter him get away with this as things did not turn out as worse as they could have been if that demon did not just seem to vanish.

However, that does not mean she was letting this Devil off thus used the Eternal Prison spell which was forbidden Sealing Magic spell. One that causes horns to grow on her head from doing so yet it was worth to ensure that the Devil would be sealed off for good,

That was at least the plan as while they still could the Devil managed to pull off one last trick before the sealing process was complete as they call the stones over and uses them to cast Reincarnation Magic on the elves, planning to return with them.

"My Prince I managed to seal away the Devil but..." Secre said him

"..."

Lemiel Silvamillion Clover was silent as to everyone it appeared he had done something to get rid of it but there nothing left behind not even proof of its existence beyond just the small battle that happened between the two.

"You seem unharmed and that good as we..." she said

Then noticed that he had one of their tools. One of them that had a spell that she had that unnamed statue sealing spell she had learned at some point during the time they had been working together. That given magic tool that contains in cause he ever needs to use for some reason.

"What are you going to do with that," the Sallowtail girl asked hoping it was not going to be used how she thought it would be used.

"..."

Lemiel said nothing once again as he had lost someone that was like a best friend for him today that was supposed to be his brother in law right now. Along with his sister and their his unborn niece or nephew.

"Do not do..." Scere started to say before the color completely drained from her body leaving her nothing more than statue standing before him with her hand outstretched. Her expression was trying to plead with him but now as a statue, it was vacant and blank.

If she had done this herself than she might have needed the magic stone to pull it off as the one way she did last time was with the help of the prince and the magic tools that they worked on.

With a heavy sigh, Lemiel just walked over to her and place what appeared to be two grimoires in her other arm that still close to her body.

Thus Secre Swallowtail rather than Lemiel Silvamillion Clover(that was not fatally wounded) was sealed away as a statue. The demon that skull should have remained behind was not there either.

However, the changes do not merely stop here as there would be many others that happened not 500 years later but various others that would happen now that Lemiel Silvamillion Clover was still around to have a deal with being the hero that from everyone else point of view had slain the demon.
