Everyone watched as Y/n not only took a punch from a monster like it was nothing but also revealed that Tsukune was his little brother.

"now then Tsukune I want you to watch carefully as this will be one of the few techniques I can teach you" Y/n said.

Just then Y/n yelled Kaioken and his energy suddenly increased by a very large amount. He went from human level power to A plus level monster in seconds. The sheer power along was enough to sent most of the crowd backward even the two large monster were thrown back.

Everyone watched as a red aura was surrounding Y/n as he stood in front of Tsukune.

"what is that" Tsukune said completely shocked.

"this is called Kaioken, its a technique that I learned a long time ago from one of my teachers. This multiples my speed, strength and other abilities I use in a fight" said Y/n as he spoke with Tsukune.

"it's incredibe" Tsukune said.

"oh believe me little brother, once I'm done training you, you'll be able to surpass S class monsters with ease" Y/n said surprising everyone.

"surpass S class, there's no way" said a surprised Kahlua.

"so Tsukune get your things together, your coming with me for a day" said Y/n.

"wait Tsukune we can come as well" said Moka only to be shut down by Y/n.

"sorry but that's not happening, I only train my family members, and beside aren't you already an S class monster" Said Y/n.

"oh come on why not" said Kurumu.

"like I said I only train family and second he'll be gone for a day, I'm sure you can entertain yourself till then" Y/n said.

As this went back and forth Y/n soon released these four won't take no for an answer so Y/n allowed a small group to accompany them.

Later

Y/n was waiting outside as he saw the small group make their way to him, in the group was Tsukune and his friends along with Kokoa and her bat, Ruby and Ginei.

"ready to go" Y/n said.

"yup" replied Tsukune.

"good now listen closely, once we begin no one is to interfere if you do I will hurt you...badly" Y/n said getting nods from them.

"we'll be accompanying you as well" said Akua.

Y/n turned around to see both of Moka's sisters. Akua Shuzen and Kahlua Shuzen. Sighing Y/n allowed it before saying that no one else is joining, as everyone doubled checked their things Y/n saw three very strange people run to them.

"who are they" Y/n asked.

"not these guys again" complained Yukari.

"friends of yours" Y/n said.

"more like annoying pests that won't leave us allow" replied Kurumu

"we are the Vampire Fan Club, My name is Kozo Kasahara" said Kozo

"my name is Kubasaki Nagasi" said Kubasaki.

"and my name is Bosaburo Taira" said Bosaburo.

"Vampire Fan Club" Y/n said confused.

"I believe that it has something to do with that girl called Moka, I can feel two souls in side her body" Lucifer said to Y/n telepathically.

As the three tried to reason with the group about letting them Join Lucifer was chatting with Y/n.

"you know I'm really getting tired of people interrupted me" Y/n said to himself.

"then my friend I have an idea, call Necro he is one of the many creatures that serve us now that we are one" Lucifer said to Y/n.

3rd Person P.O.V

As they group argued with the Vampire Fan Club and Akua, Kahlua and Kokoa just watched everyone stopped and turned around as they herd chanting.

"I summon you, one of the seven dragon King's. Hear my call and answer...Nacro" Y/n said right before a large portal opened and a large black dragon walked through.

As the dragon looked down at everyone they were shocked to see one of the seven dragon Kings in front of them.

"Lord Y/n, you have summed me meaning Lucifer has chosen you as his partner" Necro said.

"yup, I called you here because I need you to get rid of these three as well as anyone else who gets in our way" Y/n said while pointing to the terrified trio.

As Nerco chased the three Y/n began to leave with the others following behind him.

Timeskip

After leaving Yokai Academy Y/n had used his Instinct transmission to teleport everyone to a strange place.

"where are we" asked Ruby.

"before we train I thought it would be best to address an issue with Moka. Two soul for one body is a very bad thing, if left unchecked they could both die" Y/n said.

Everyone looked worried especially Tsukune.

"wait, what do you mean they could both die" Tsukune said.

"its as I said, but luckily I have a way of preventing that for happening" Y/n said.

As everyone followed him they soon entered a room and in it was a large throne.

"what is this place" asked Akua.

"we are currently in the middle of reality it's self, and this is where the strongest being lives" Y/n said but soon giggling was heard.

"oh Y/n, your so sweet the way you speak about me" said a strange voice. As everyone looked around they saw a golden blur shot past them.

"their fast" Kurumu said surprised making Y/n sigh.

"did I also mention that their also the most annoying" Y/n said.

As everyone was looking around only to see someone sitting on the throne now.

"it's been a while Y/n, here for another fight" said the stranger.

Y/n grunted in annoyed while everyone was confused.

"um Y/n, who's that" Tsukune asked.

"that would be the stronger fight in all thirteen universes, Super Shenron" Y not said as everyone surprised as the small person in front of them was the strongest in thirteen universes.
