Cannon is near

Five whole years have passed since Kaji and the girls returned home from the world of dxd. When they returned Kaji noticed that almost no time had passed in this world, he didn't know why, but he started researching space, and dimensions. This in turn led him back to the library, where he would bombard Beatrice, with questions on a daily basis.

While he studied, he didn't neglect his swordsmanship and other abilities he had gained. One of the more useful ones was touki, which would let him utilize his own ki or life force. As such, it results in a tremendous increase in their offense, defense, and speed. However, some have trained their bodies to the utmost and gained extreme vitality. This even allows the user to counter magic attacks by punching or otherwise striking them.

He could now control holy power to an extent, and there was something he discovered when he experimented with this power on mabeasts. Holy power was the bane of the beasts, once Kaji used a small dagger made of his holy power to try and cut the beast. And the results were astonishing, the knife cut the beast-like butter, but there was more, the pain the beast felt was amplified to unknown amounts.

Kaji managed to become one of the strongest swordsmen in the empire of Lugnica, the only ones who knew of his swordsmanship skills were Ram, Rem, Frederica, Reinhard, and some others, which included Roswaal. Kaji had made a tremendous leap in skill and strength, and now he and the twins were waiting at the mansion door for the arrival of the clown. Before leaving, Roswaal informed them that he would be bringing a guest of utmost importance to the mansion.

While they were waiting, Kaji was a bit existed, after all, the canon would soon be starting. He wanted to see how Subarus return by death looks from his own point of view, he wanted to know if he would be able to remember the events that happened after Subaru dies, or would he be like everyone else, without the memory of anything happening.

But soon his thoughts were interrupted when he saw the clown and a silver-haired half-elf. Who just arrived back at the mansion, and Kaji couldn't help but notice the almost depleted mana reserve of the clown. He looked prim and proper, but he most likely fixed his appearance with magic, before returning. Roswaal noticed how Kaji looked at him, and wondered what the Oni was thinking.

Surprisingly none of the three onis greeted the man, it seemed like they ignored him even though he was the lord of this house. While the half-elf girl was looking at Kaji with eyes full of curiosity, she was wondering what he was at this moment.

*Ahem* The man with the clown makeup cought before starting to introduce the girl to the three of them, and the three of them to the girl.

"Soooo, let me introduce you, this is Emilia treat her like she was the one in charge of everything here. Now then Emilia if there is anything you need, go ahead and tell it to any one of them as they will prepare everything you might need now and in the future. These here are Rem, and Ram, while the boy is Kaji, feel free to ask them if you have any questions." Roswaal said before leaving, it seemed like he was tired, but not like anyone cared about that.

*sigh* "Then Emilia follow me I will show you to your room, where you can rest." Kaji said after sighing.

"Oh, uh, yes!" The half-elf girl said while following after the Oni.

Emilia is a beautiful Half-Elf with long silver hair and purple-blue eyes. She wears a white and purple outfit along with a white flower in her hair. Although she appears to be in her late teens, Emilia's chronological age remains unknown, though mentally she seems to be in her mid-teens.

While leading her to her room that was prepared beforehand, Kaji would glance at the girl from time to time. She was a beautiful girl in her own right, and While looking at her Kaji could understand why Subaru would fall for her. After a couple of minutes, Kaji had led Emilia to her bedroom, but before he could leave he was stopped by her.

"Umm, but can I ask what you are…... I don't mean to be rude, but I was just curious." She asked while looking at him.

"...An Oni…" Kaji said while looking at her, then he looked at a green-colored crystal that was below her neck. And the moment he looked at the crystal, he couldn't help but smile, he wondered whether he could take on Puck in an all-out fight.

And a moment after Kaji looked at the crystal, it shone, and a small furry cat-like creature popped up, it was Puck.

In his smaller form, Puck stands at nine centimeters tall and is small enough to fit in the palm of a person's hand. Aside from his diminutive stature and the fact that he usually stands on his hindlegs, Puck is fairly physically reminiscent of a common house cat, specifically an American Shorthair. The light grey and white fur that coats his entire body is well-groomed and very soft. His eyes are icy green and his pink nose is another trait that separates him from a house cat. Puck's tail is abnormally long to the point that it is the length of his body and his ears are floppy yet extremely soft to the touch. On his left ear, Puck wears a single golden hoop earring that makes his ear droop down.
