From Becoming the Master of Monsters

The main reason why Yasaka came to Kuou Academy was naturally because he wanted to get closer to Yuuto. Moreover, Yasaka was always wary of Rias and Sona who came to their house before.

Kyoto Yokai finally had hope of becoming glorious, but the existence of Rias and Sona always made Yasaka feel uneasy.

You must know that "devil chess pieces" can make other races become "reincarnated demons".

What if my elder brother cannot withstand the temptation of those two demon girls and becomes one of his family members?

My brother is currently the strongest among youkai. Even if you have the idea of ​​​​continuing your bloodline and having children, you should first consider their monsters, so as to ensure the purity of your bloodline.

So in order to prevent his brother from being deceived by the devil, Yasaka decided to come to the academy in person to protect his chastity!

However, what Yasaka doesn't know is that Rias, whom she regards as one of her biggest enemies, has no time to attack her brother at this moment because her own troubles have also come to her door.

Today's Supernatural Research Laboratory is quite busy. In addition to Issei and Rias and other family members, there are two other new faces in the department today.

These two unfamiliar faces are a man and a woman. The man has blond hair and a very cool hairstyle. He is wearing a burgundy suit. He is sitting on the sofa with his hands spread out and his eyes are unscrupulous. He looked around Rias's body.

As for that woman, she is a cold beauty whose appearance is not inferior to that of Rias.

In terms of figure, she is slightly better than Rias, and it is estimated that only Yasaka can compete with her.

However, it can be seen from the positions of each other that the cold beauty and the man in the suit are not together, because the silver-haired beauty in a maid uniform has been standing behind Rias from beginning to end.

"Gurefia, I've already told you that I want to arrange my own marriage. You guys are so capable of making decisions for me. Have you ever asked me for my opinion?"

Facing Rias's question, the silver-haired maid behind her also maintained a serious expression and said: "The marriage contract between Lady Rias and the Phoenix family was decided by the head of the family himself, whether it is me or Sirzechs Sir, no one has the right to interfere.

Moreover, the two families have made an agreement before. In order to ensure the reputation of the Gremory family, Rias-sama is also asked not to be willful. "

Rias originally wanted to say something, but the silver-haired maid named Gurefia seemed quite majestic. Rias just stood up and wanted to say something, but she quickly sat down again as if she was discouraged.

"Rias, you should also know that since the war between the three parties, there are actually not many pure-blooded demons in the underworld now.

And we are both superior demons of the Seventy-Two Pillars of Demon God. In order to ensure the continuation of our pure bloodline, the Gremory family and the Phoenix family arranged this marriage.

Originally, I was worried that if my fiancée was an ugly girl, I would not be able to swallow it, but now it seems that you are much better than I imagined. "

The blond man in a suit is named Rysel Phoenix, the third son of the Phoenix family, and both pure-blooded superior demons like Rias.

Because of the special situation of the Gremory family, Sirzechs, the eldest son who was supposed to inherit the Gremory family, became the Demon King, which led to his sister Rias becoming the heir to the head of the family.

Although Sirzechs still has a son, he will also become the successor of the Demon King in the future.

Therefore, it is not an exaggeration to describe the current situation of the Gremory family as being sparsely populated.

As one of the few demon families in the underworld, if they don't even have a candidate heir, it will undoubtedly be a huge failure.

As the sole heir of Gremory, Rias, what if something unexpected happens in the future? Will the Gremory family be completely destroyed?

Therefore, the current head of the Gremory family, Rias's father, has been eager to arrange a marriage partner for Rias and hope that she will give birth to an heir soon.

It was also for this reason that Rias took refuge in the human world alone.

But because of the fallen angel cadre's attempt to attack Rias, although nothing happened in the end, it sounded the alarm for the Gremory family.

Rias has a strong personality and likes to take risks. If they don't leave an heir to the family, they will never be able to rest assured.

It is also for this reason that Risel and Gulefia appear here.

To become Rias's marriage partner, ordinary people naturally cannot do it, and as Rias is the heir of the Gremory family, the other party must also marry into the marriage.

Nowadays, there are not many pure-blooded high-level demons, and even fewer agree to marry into the family. Therefore, the Gremory family also wasted a lot of effort on the engagement between Risel and Rias.

"Are you kidding? How could the minister marry such a person?"

When he heard that Rias was going to be forced to marry someone else, Hyoudou Issei who was present immediately exploded.

Although Issei didn't know or be familiar with Risel, as a pervert, Issei could tell at a glance that he was definitely a pervert.

But even if they are both lustful, there is a corresponding chain of contempt. Although Issei is lustful, he will never give up.

But Risel, at first glance, looks like a typical playboy, who doesn't have much affection for women, and is the kind of Neptune-type scumbag who just throws them away for fun.

Just from the way the other party glanced at Rias' body just now, it can be seen that the other party is not a good person at all.

Marrying such a person would undoubtedly push Rias into a pit of fire.

"What do you mean, this is a marriage between pure-blood superior demon families.

Rias and I are both pure-blooded high-level demons. Do you, a reincarnated low-level demon, have the right to speak here?

Could it be that as a mere dependent of Rias, you still have some unreasonable thoughts about Rias herself? That's really hilarious. "

Seeing Issei rushing forward with an excited expression, Rysel still had a arrogant attitude, and with a casual slap, Issei was thrown away.

And just when a ball of flame ignited in his hand and he was about to throw it at Issei, Gurefia from before appeared in front of Risel without any warning.

"Please stop it! After all, he is Rias-sama's dependent, so he is also a member of the Gremory family.

If Mr. Riser's methods are too drastic, I may take certain measures to calm you down. "

Looking at the silver-haired maid in front of her, she was as unruly as Risel before, but now she couldn't help but choose to give up.

Because the silver-haired maid in front of him is no ordinary character, but a being in the underworld known as the "Silver-haired Queen of Annihilation". She is not only the queen of the devil Lucifer, but also known as the "strongest queen" in the underworld!
