---------------------------------------------------------

After being thought to have died during the fight of a sudden appearance of seemingly undefeated Demon...

Sei wandered all the way to the Spade Kingdom for answers, then,

Seishiro became forgotten by the whole Clover Kingdom the moment Julius died. They face demons from the ♤ Kingdom  after facing Litch's group only to discover Sei and his spirit is working with them, not knowing Sei is only doing so for the sake of keeping the Black Bulls from harm. But due to a sudden action from the clover Kingdom Sei witness what happened to Yami and Litch, and was forced to leave the ♤ Kingdom to support the Clover Kingdom, since the ♤ Kingdom break their words "to not harm the Black Bulls" Sei, introducing himself by his real name, sided with the while Clover Kingdom. It didn't went well of course since no one remember him he went through such kengths as to hold back his sadness and pain for being forgotten. Even Yuno said the mist awful things.

"I don't remember being close to the enemy." - Klaus.

"I don't have any memory of knowing you." Noelle.

"I can't remember all the members Yami-san accept but... if you are part of the black bulls then that explains why you suddenly switch sides and ask for a favor to save Yami-san." - Finral.

"I don't remember growing up with a demon and a spy. Looking at you disgust me... will you please stop approaching me?
...Did you really expect I'd kiss you?
...Get lost.
...I have no feelings for you, in fact I feel hate for you but you sure are useful.
...Just disappear." - Yuno.

"Huh? I understand the reason but... WHAT?! You're Captain Yami's relative?!
...Yuno huh, well he's always been a jerk but he's a nice guy.
... don't worry, even if he hates you, you have us the black bulls, and Yami-tanjou's family is my family.
...I mean you came back to save Yami-tanjou because you're kind right? And worried? There's no way you're a demon, after all you have emotions, unlike them. You used your magic for safety instead of danger, so you're human, you're you." - Asta.

As Keiser, he helped the Clover Kingdom only to realize the friend of his Father, The Wizard King... is the real enemy. Having enough, gaining anger for knowing Julius is the cause of their death and the one who made changes in the true story of his parent's death, Keiser killed The Wizard King in his own hands. Everyone are surprised by Keiser's great hatred and the Wizard King being able to remember him and connected to him. No one can survive once they trigger an elemental's grrat hatred. However due to such actions a self-proclaimed God appeared taking Seishiro's grimoire.

"Your powers are too dangerous. You are too strong, but... I will let you weild a few magic."

After that the Grimoire of 5 leave became 4 leaf with mixture of 6 colors revealing 6 magic type. Keiser was thankful knowing he also change inside by what happened and use light magic to heal everyone. And in exchange of his grimiore changing, Jonah... disappeared. Losing a companion is too much, but for the people of Clover Kingdom, it is one of the great sacrifices of someone worthy to be called a hero. Sei was offered to be Wizard King but he looks at Yuno and Asta and said. "Even if I were forgotten, my true dream and plan in life will never change. And I wish for a peaceful life, so I humbly decline." Seishiro responded and announce he's leaving right this instant. Everyone in the Magic Knights bid him farewell but for some unknown reasons, Asta and Yuno find it heartbreaking. Sei who is now Keiser Eineheit Ashmund (I miss spell it at some chapters away)
