We're following the story of the mc named yasuke,He's a 16 year old higschool student
who has a secret crush that even his friends don't know about,but before he could confess to the person he got into an accident and died when he woke up he found himself lying in a large room.

Without knowing where he is he screams in anger and sadness,because he knew that he died before completing his long lived mission of confessing to the person he loved.

after sitting for a while he got himself together and stood up he looked left and then right when he looked behind him he saw three people looking,two people who were wearing heavy armor and one really suspicious looking person in a robe,after a while the two knights grabbed him on his arms and took him with them,they then came to a big hall with a lot of people and a man sitting in the middle,as he was thrown forward he fell down trying to get back up he was pushed down by something unknown,the people were staring at him and whispering to themselves the man in the middle then silenced them and stared talking "oh chosen hero you are blessed by the goddess Athena with the holy powers of the divine spirit,...now rejoice my people of salvatora your saviour is here"...yasuke thinking (what is going...on and where the hell am i) just listened to the man speaking he said "oh chosen hero from another world you are chosen because you died in your old world,so you are to save this one then you can get back to your old word,but only after defeating the demon Lord.
