The princess was actually dead since the previous night by poisioning her. And the culprit were? The servants. They killed her under the order of vampires that if they sacrifice the princess, the lord of vampire will arrive in place of her and the Vampires will have to suck her whole blood to take her powers and will defeat the demons and will dominate solo in all the races.
"... True, she is saying true." Said Sky Knight by using his Lie Detection power.
"Um... I apologise, will you not break the promise we made?" Asked Aqua with try to ask for forgiveness by Angel.
"No, I don't mind that. You were doing your job so I don't mind." Said Angel and Aqua became happy and once again hugged Angel and said, "Sister is the best!"
Earth Knight raised his hand and asked, "But why they work for vampires?"
Because they pray for them. With the existence of evil races, human were also seperated in various groups. Some were still against demons and vampires, some prayed and considered demons as God become one and some were those who prayed for vampires and wanted to become one as well.
"So, you mean they are those people who prayed and did rituals for Vampires? Interesting." And Knight Earth was actually interested about the case.
But Anish was having one doubt and he asked, "So you told us that you are a reincarnated person who has came from another world and this morning when you wake up. But--"
"No, I don't think that I have came here at morning. My guess is that I came last night from nowhere and servants picked me up because they tried to show me as the princess in place of actual dead princess in front of the king and queen. Or they considered me as the supreme Vampire."
Yes, Angel told about the thing that she is a reincarnated under the talk of System and he actually allowed him but just said to not tell anything else except that she's a reincarnated human.
"Yes, yes. Whatever, my question is... How do you know this far if you have just came here last night?" Asked Anish and all Angel's face faded and she started sweating too much.
When Anish saw Angel sweating and hesitating to say, he freely ordered, "If you don't want to tell, then don't. Whatever you have told is enough and the case is finished. So you can breath again."
And finally Angel got a breath of relief and said, "... Thanks."
"Si~ster, let's go and I will give you a great costume!" Said curious Aqua and holded Angel's hand and started running and Angel.woth enjoying followed her.
"Why did you allowed her to not tell? It's my first time watching you leaving someone." Asked Sky Knight.
Anish opened his mouth to response but stopped there only because he was having no reason to do that.
"... I don't know, but I guess she's not our opponent, at least she doesn't looks like to be. And as she said that she's a reincarnator, she has just came and will leave after dying. The things will matter when she'll come in our way." Answered Anish and started leaving.
"Anish is cool, of course he is." Said Agni with a smile on his face and started following him. Others also took their leave.
In the novel, the princess' death and the reality behind the servants was exposed sooner. But after the death of them because the same demon arrived and attacked at the castle in task of finding and hunting the "Vampire Supreme" so that despite of Vampires, Demons would've dominated but in the novel, actually no Vampire Supreme arrived on the sacrifice of the princess. And by this fact only, Angel was confused and realized something.
'I... Maybe am not any character in the novel!' thought stupid Angel.
And Angel also sooner realized her stupidity, she has came to change the future and save the other Knights of the novel so how can she herself be a character?!
'But... Come to think of it, in the novel I never saw the Demon King and Vampire Queen and neither their fight against Anish, the God Knight, defeating them.
And about recognising them, when System was transferring the whole novel in Angel's head, he also saw that how they look so it was no problem and she also knew that Knights will definitely come like they came in the novel.
'Mister System... Are you here?'
"Come on sister! Hurry up!" Called Aqua and she was in front of a costume shop which was having almost no customers. Angel stopped thinking and with smile followed her and entered the shop with Aqua.
"Uh... Anish is a bad boy." And Agni was stalking Angel and Aqua outside the shop hiding between a thin street. And his reason to stalk was because of Anish's order!
Anish couldn't easily trust on Angel so he send Agni for the task!
"Ohᡣ𐭩, you are looking so pretty sister!" Complimented Aqua and the view goes on Angel and she was wearing a blue - black costume and it was actually looking pretty on her.
"... Something is missing." Said Aqua and went to somewhere and came back in a second and it were small blue clutchers and Aqua put it on her hairs and now she was looking more beautiful!
"Thanks sir for the costume!" Said Aqua to the shop owner who was an old man and he with a smile said, "Haha, I am happy you and your friend liked it. Keep on coming and buying new costumes, Aqua."
And Angel and Aqua with thanking left the shop.
But suddenly when Aqua got out of the shop, she felt of someone and suddenly disappeared from Angel's eyes.
"Were..."
Aqua was troubling someone at his head and teaching a lesson.
"... You... Watching us inside the shop?" Asked angry Aqua.
"N-No! Definitely not! I am here since you and that girl entered the shop! And after that, I was just waiting for you!"
And it was Agni being troubled by Aqua and now has to give evidence to prove himself not a culprit!
