'No, I couldn't it won't be as easy to cover as just killing a few animals' Rio thought however contemplating his decisions as the EXP probably gained from killing a human is much higher and more rewarding than killing animals.
Rio decided to go ahead with his thoughts and brainstormed about finding a way to take a life without people noticing or at least not discovering it was him
Rio went to talk with the maids as they were kind of his source of Intel about what was going on in and out of the manor. It was quite easy to make them let their guard around him as they realized he was not much liked in the family and often spoke with them, as he was growing up, so most saw him as a little brother rather than being polite to him for his position (of course there were some exceptions) however you can't make everyone happy.
From the latest gossip, there seems to be some hidden hatred between the head maid and the head butler. They both had different responsibilities to avoid a clash of authority however it seems one of the servants harassed was harassing a maid. The maid decided to make a complaint to the head maid and in turn, decided to scold the man and threatened to make his life a living hell.
The man couldn't stick up for himself with his inferior position and decided to go to the head butler for help, which the head butler took up and went to the head maid trying to reprimand her saying that she was stepping outside her authority. It seems the servant may have stirred some trouble by mixing in some lies as well. For the Head butler to reply to the situation with such anger.
Now there is high tension in the air for both the servants and maids. 'This atmosphere is perfect for me already; Rio could now just poison the accused servant and everybody would just think it's the maids that committed the crime' Rio smiled wickedly while thinking of any loopholes that could be found.
Since Rio has thought of this plan from every perspective he can say that all fingers would definitely not point at him and would further increase the tension between the maids and servants which he could select another victim.
Rio went to the bushes and found some poisonous flowers there, the servants are supposed to remove them fortnightly as they often grow with the flowers planted. Rio grabbed only the needed amount since there was no point in carrying a lot on him
"Alicia don't you think the tension in the manor is too high between the maids and servants, if this continues it will probably affect the performance of the maids and servants which could dissatisfy Father" Rio spoke in a volume that wasn't too quiet but loud enough for everyone in the room to hear him
Everyone heard what Rio said and silently agreed, Rio interrupted their thinking " I feel like someone should send a message to the head maid and the head butler for them to reach common ground and settle the matter, to not affect the working environment."
All of them nodded as a sign of agreeing with his opinion, and they proceeded to walk to the head maid and discuss what Rio said. The head maid was a stern but knowledgeable woman so she, of course, knew that the work environment should be affected by emotions she decided to invite and converse with the head butler where everything got resolved and everything was sound.
A day passed and the atmosphere, though still tense, got a slight bit better. So Rio decided to initiate his plan. The servants had their quarters where a group of them lived. Rio found out which quarter was the accused servant and realized he usually goes to his quarter 30 minutes before the rest. Rio waited for the next night to commence his plan and quietly made some porridge and added the grounded poison herb.
When Rio placed it on his particular bedside cabinet with a note 'I'm sorry for blowing the situation out of proportion. Here's my apology' in handwriting as close as possible to the maid's one. (All of them are literal to perform complex tasks without trouble. Rio just took one of the letters she wrote to a shop regarding some dresses)
Rio headed back to his room and waited to enjoy the show while waiting he decided to check his status.
