Your story in a Demon Slayer part 1

Diagnosis results Pengu Konton was a simple human, but one day...Pengu Konton were hanging out with his/her friends at night. After some time, Pengu Konton decided to live his/her friend because Pengu Konton felt tired. While walking home, Pengu Konton heard a scream from direction where he/she and his/her friends parted their ways. Pengu Konton being a little worried, decided to go and take a look what is going on there. As Pengu Konton arrived to the place where screams were coming from, he/she saw a demon surrounded by guts of Pengu Konton friends, devouring them. As fast as he/she could, Pengu Konton ran away in horror, trying to save his/her life.

That event made Pengu Konton hate demons. After recovering from shock, Pengu Konton realized that if he/she not going to do anything, something like that horrific event may happen again, and who knows if Pengu Konton will survive the next encounter with a demon.

Pengu Konton decided that he/she need to know more about demons and how to deal with them. Eventualy during the Pengu Konton research, he/she met a slayer, who appeared to be a Shinobu Kocho. After hearing Pengu Konton story and all the determination and zeal in Pengu Konton voice, Shinobu Kocho decided that Pengu Konton has a potential to become a slayer, so Shinobu Kocho offered Pengu Konton to became his/her sensei, and of course, Pengu Konton agreed. (Your sensei - your breathing style)

Training was tough, but Pengu Konton determination and zeal helped him/her to endure everything that Shinobu Kocho made Pengu Konton went through. At the end of the training Pengu Konton became much stronger and ready for the Final Selection...

Final Selection was hard, really hard. But by cooperating with other slayers and maybe a bit of luck, Pengu Konton managed to pass.
As Pengu Konton got his/her ore for nichirin, Pengu Konton asked it to be a...Naginata.
After Pengu Konton got his/her nichirin weapon, it took a blue color...
