Story-8
So coming to the premise, the MC can see premonitory corpses and the time of the death of a person one day prior. So what does she do? She goes around telling people that they are gonna die tomorrow but saves them in the nick of time, almost every time which has caused her to earn the ire of her classmates and attaining the moniker of "Liar Satsuki". But you might be wondering why isnt she called a hero then? If she saves people? Pretty simple actually, it depends on the circumstances.
Be it saving a person from a football coming to crash into the window to cause its splinters to impale someone's neck or a signboard falling at an angle which beheads a person, our MC never gives up. The deaths might be outrageous, but you can see that the mangaka has some medical knowledge, as MC's father is a doctor and also her attempts at saving a kid who was choking were pretty accurately depicted.
Art-6
Art is pretty mediocre if I am being brutally honest but it isnt like its un-readable or anything. Slowly but surely the quality of art is also improving with upcoming chapters.
Character-8
Now, this is where the manga shines, the characters are different and all have a role to play in the story with sprinkles of character development. MC probably has a regret when she chose not to use her power to save someone in the past leading to her "overly-good" nature of saving everyone. Also, one of the closest person to her is actually quite mysterious and I might just be speculating at this point but I think averting her death might have a negative impact on the story later on.
Enjoyment-7
All in all the story has been setup in a terrific way for now, although it has still not capitalized on its full potential in my opinion.
Overall-7
The pros of the manga have been that it has been quite enjoyable until now with little twists along the way. Some mysterious characters have been introduced and the story is looking to take an interesting turn recently as her power was not able to correctly identify the time of death of the corpse and also for the first she saw her own premonitory corpse. So, this manga has massive potential to become something bigger.
Although some cons which I found out were that her school is too dangerous of a place if there are premonitory corpses appearing on a daily basis and also no explanation about her obtention of such a power has been touched upon till now but I'm sure that it will be explained in the future. Also, in the earlier chapters, no boys were present so I thought it might be an all girls school but recently a major male character was introduced to establish it as an co-ed.
