Who is Xin?

Xin sitting in front of them, Koneko who was beside him eating sweets, while Melan stood behind Xin.

Sona and Rias staring attentively at this kid, while Tsubaki looks at them vigilant, Akeno who's in deep thought.

Meanwhile, Issei and Kiba are trying to fix the door that they just destroyed.

Tock!Tock!Pock!Tock!

Issei asks," Can you move it a little higher?"

Kiba said," Sure,"

Tock!Tock!Pock!Tock!

Rias asks," Can we now finally hear your answer? "

"Why the Red Dragon Emperor and a Fallen Angel following you?"

"And how did you avoid our scan yesterday when you entered my territory?"

Xin said," Well, I enter here normally, I see that the school has a protective barrier and scanner but …."

He feels embarrassed to tell them the reason, he won't want to offend them after all.

But still he told them the reason," Well ….. Because your scan is too weak that's why you guys did not detect me and Melan when we enter in this school"

Sona adjusts her glass and says," Too weak? Do you know how powerful the scan is in this school?"

"It can even detect Ultimate Devil or a 6 Wing Angel"

Xin shrugged his shoulder helplessly, well he really can tell that the barrier and the scanner of this school are weak.

Sona asks," Then what about the Red Dragon Emperor, why is he with you?"

Xin said," Oh the Pervert Dragon? Well yesterday night he almost killed by a fallen angel because of his secret gear"

"I save him and take him as my apprentice, well after all he is only a human and stupid too, if i don't help him he will going to die again in some other place"

Issei shout back," Little Master, I'm pervert but I'm not stupid enough to get killed again!!"

Xin said," Stupid! Do you know that you have internal injuries because you used boost once? Thank goodness you eat the energy bar that I made for you or else your dying right now"

Tsubaki said," President he is Issei Hyoudou from 3-B, one of the "Perverted Trio" in our school"

Sona stare at him and said," So he is one that famous pervert"

Rias asks," So what about my Devil Piece? How do you know that information?"

Xin said," Well if you ask me how I know ..... I just know everything that all"

Rias is still looking at Xin, she did not buy his reason, while Xin doesn't know how to respond to her question.

Xin said,'' Well ….. I have same thing like Evil Piece so I know that thing"

Sona and Rias were confused, they do know that there's only 1 set of the evil piece for each clan and the clan leader only gives 1 set for each outstanding devil in their clan.

So how Xin said that he has the same thing as them when he is only a human.

Xin said," Actually it's not an evil piece that you guys have, but it same as how it created and the use of it"

He then take out a gorgeous box in front of them and put it in the table, he look at them and said," This is mine, i only used it once so I think they all still complete"

Akeno who's deep thought suddenly shaken after seeing the box design, she hurriedly asked," Can I open it?"

Xin nodded, "Sure"

Rias hurriedly stopped her," Akeno stop, don't open it, maybe it's a trap!"

Akeno said," No let me open it, i feel I know what this box is"

She walks and slowly opens the box, all of them see an 11 piece of exquisite keys, they even see the constellation inside of the crystal keys.

Akeno was shocked," This is the Twelve Constellation Keys!"

Rias and Sona were look and see a beautiful key but they didn't know what it.

Akeno stares at Xin and slowly her memory from her childhood starts to come up, the kid who saves them from death, the kid who likes to play all over the place and the kid who saves her mother and changes her to a much better one.

Akeno stared at Xin and said," So your back Xin?

Xin smiled at them, he look like a very handsome sunshine boy.," Well i just arrive last week"

Aken then stared at Melan who was still expressionless, she said," So this is Melan-oneesama?"

Xin said," She can't remember you after all, you still child when we left"

Akeno walked up to Xin And hugged him tightly," Thank goodness your back, Xin-kun…."

"And you did not even change after 8 years ~"

Xin said," Well, we really not going to change after all we time travel here"

Issei asked," Little Master, are you Doraemon?"

Xin said," Issei i think we need to add more training for you"

Rias asks," So you know Akeno and Koneko? Then who are you?"

Koneko said," Xin is a robber"

Akeno," A hero"

Issei," Little Master?"

Melan," ….. Master.."

Rias feel that her head is going to explode, Xin did not even answer but she already heard 4 different answers from them.

Xin smiled at them and said," I'm Xin, Xin Fei from the Otherworld, nice to meet you guys ~"
