"Then... Can you heal my sister's disease?" Said Charles.

When Augustav and Anne heard this from Charles, they could only stay quiet as they were a bit surprised.

Tetsuya who heard this from Charles is actually already aware of the existence of his sister, as both of them are twins. The name of Charles's sister is Katherine E. Changaire, who is the princess of the Empire. Katherine herself isn't a secret to the public as everyone in the empire knows her as a princess who is experiencing an incurable disease.

The disease experienced by Katherine is actually a disease that can make the people who experience it slowly dying as their organs slowly start to rot at the age of 4. Why the age of 4? It is because the disease can only happen to a newborn baby, but the percentage of getting hit by the disease is so low that almost no one can get hit by it. But unfortunately, Katherine is one of the people who is not included in the people who don't get hit by the disease. The name of the disease is Hormoid, which Tetsuya found out is one of the deadliest diseases in Akame ga kill world.

Tetsuya then looks at both parents' eyes as their eyes full of hope since he knows that many doctors tried to cure the disease of the princess has but failed, but since he can remove the poison inside Augustav's body that many doctors failed, they now can see new hope in front of them. Suddenly a notification appears in front of Tetsuya.

------------------

Cure the Princess of the Empire

◉Difficulty: B+

Katherine E. Changaire is a princess of the empire as she has a twin brother named Charles E. Changaire. But due to a sickness called Hormoid that she suffered when she was born, her organs started to slowly rot when she reached the age of 4. Save her before she dies of the sickness that she suffers.

◉Clear Conditions:

▪ Cured the Princess before she dies (Time left Before death: 7523:34:25)

◉Mission Reward:

▪ [Decay]

▪ Obtained 3.000.000 System-point

▪ Obtained 1.150.000 EXP of [STATUS] Level

[Accept] [Decline]

------------------

When Tetsuya saw the notification, he somehow found this a little bit surprising since he didn't expect to get a mission related to the princess even though he decided that he was going to help Katherine even from the start.

'7523 hours huh... That means the princess herself can only live less than 11 months.' Thought Tetsuya as he looked at the clear condition. He then also looks at the reward that is he gonna receive from the mission, unlike the previous mission which is an A+ difficulty mission (Referring to the mission that kills Honest and cures the Emperor) this mission is a B+ difficulty mission, but the reward that the mission gives him is slightly different as the exp he receives from the mission is a bit less than the exp he receives from the A+ mission, likewise with the system point that he receives is more than the A+ mission system point which makes him happy. But what most intrigued him is the reward that he will receive which is [Decay], as he probably thinks of it as a skill that can make something rot, but he will see until he gets to see the skill directly.

Tetsuya then accepts the mission as suddenly he could hear a voice.

"Can you cure my sister's disease?" Charles once again asked with a worried expression on his face, when he looked at Tetsuya who stayed quiet.

"Ah sorry, I was just thinking of something, and the answer to your question is yes, there is a chance I can cure your sister," Said Tetsuya with a smile on his face.

"Really, can you really cure Katherine?!" Said Augustav, while Anne is also looking at Tetsuya as both of their eyes who heard this now can see a glimmer of hope in curing their daughter.

"Yes, at least I can try," Said Tetsuya while nodding at both of them.

After hearing that, Tetsuya could see Augustav and Anne let out some tears, and as for Charles, he could only smile happily that there is a possibility that Tetsuya can cure his sister.

-- Katherine's room - The Empire palace --

Inside the room, there is a 6 years old girl who is lying on a bed with a frail body. Because of her Hormoid disease, her body is so thin. If she didn't get hit by the disease, her appearance would be a beautiful girl with green long hair and also green color eyes. Her name is Katherine E. Changaire, the princess of the Empire.

Katherine who is alone inside the room could now be seen as she is reading a book right now while lying her body in the bed. Because of her disease, she cannot walk around as she can easily get injured due to how frail her body is. At the age of 4, She just realized the disease in her body when she was walking around the palace and her legs were starting to feel weak, after knowing that she suffered from Hormoid disease, her parents which is the Emperor and the Empress are trying many ways in order to cure her disease but to no avail, her disease cannot be cured.

Most of the doctors who were trying to cure her also said that most of the victims who get hit by this disease only live until 7 years at most and at the moment she right now is 6 years old which means that there is only less than 1 year left before her death. Katherine who heard this at first is scared that she will die but after a few months she starts to accept her fate but she is still sad that she is going to separate from her family when the time comes.

"Why are they hiding things from me? Is it because they are worried about me?" Katherine asked herself while implying they to her family as she then looks at the ceiling with a confused expression. Truthfully she feels lonely since her family started to rarely visit her, and this started 3 months ago. She doesn't know what happens outside her room due to the fact that no one tells her what happened, so she never heard the fact that Augustav got poisoned.

The reason why no one tells Katherine is due to Augustav forbidding anyone to inform her about his condition to Katherine since he is worried the news about him will make Katherine worried and overstress her body. But due to her mother and brother always visiting her, she knows the gist of the situation.

Katherine is able to deduct that something must've happened to her father because her father never visits her since the father that she knew almost always visit her every day, and secondly, after seeing her mother and her brother face to face when they came to visit she figured out that there is something happen to his father which she knows as she can grasp the way they are talking and their facial expression. She figured out that something is happening toward Augustav after asking Anne and Charles, since both of them lied to Katherine.

As a 6 years old Katherine is good at figuring out whether someone is lying or not, whether by looking at their facial expression or voice. She is also quite intelligent due to reading too many books for her age which makes her a bit too mature for her own age. Though her parents and her brother don't know about her talents since she doesn't show her talents to them.

"Father... What happened to you?... What if I died while not knowing the truth?" Said Katherine as she looked at the ceiling with a frown on her face.

Tears then start to flow out from her eyes as she picks the book and hugs the book as the book is in the center of her chest. The book that she hugs right now is a fantasy story about a knight saving the princess from a dragon. Even though it's a cliche book she still likes the book. When she looks at the book she starts to imagine that she becomes the princess in the story as she then can only wait for the knight to rescue her from the dragon. But the difference between the story and her life is that the dragon is the disease, and she is just like a princess who doesn't have a knight to rescue her. She could only accept her fate to death.

'If only there is a knight just like the story that can save me from this state...' Thought Katherine as she can only one day someone is going to cure her even though it's impossible. She then slowly closes her eyes as she is about to sleep.

Suddenly there is a knock from the door which awoke Katherine before she is able to go to sleep.

"Who is it?" Asked Katherine while looking at the door.

"It's me, Katherine," Said Anne as she then entered Katherine's room.

"Mother!" Said Katherine with a happy smile.

Anne then enters the room followed by all the people from the Emperor's room, this causes Katherine to get confused as she doesn't know what happened. But when Katherine looks around Katherine finds one person that she does not recognize, and soon both of their eyes meet with each other. Suddenly Charles runs toward Katherine and then says something to her.

"Sister, your disease can be cured now!" Shout Charles with a happy smile.

"Eh?!"
