177013 Manga is also known by the 'Metamorphis Manga/Emergence Manga'. Shindo L, an American-Japanese mangaka, is the author of this manga. It was published between 2013 & 2016. This manga gained popularity online due to its dark and sad content. It is a hentai doujin. The main character is a girl and her name is Saki. At the first glance she looks quite depressed herself. We learn that she used to be quite popular with her friends, but she is now not as cool. So, in order to look cool again Saki decides to do a makeover.
Here we get to know about why the manga is also known as Metamorphis. Just like in Metamorphis, there is evolution. Saki looks as if she has just evolved after her makeover.
She decides to spend a weekend outside, get some fresh air, and purchase some fashion magazines. There we meets the other character of the story whose name is Hayato. Basically what he does is flirting with her, and he succeeds too. He finally took Saki to karaoke.
They enjoy singing in karaoke, but it's not only singing that they love. Hayato is a master at getting around girls, so he bought a pill that will increase the pleasure and give it Saki. They have a great time in the room and Saki is in an awful state. Hayato leaves her drugged.
Inside of Hayato's head Saki is just a toy for her and he add his contact in Saki's phone and Saki's in his mobile phone. So, he can call and play with her whenever he likes.
Why am I seeing the number 17703 in Anime Communities?
This question can be answered very simply by saying "it's just a meme". The manga have been trolled a lot and the reason for missing the number'1' is because The number refers to index/submission id (it comes on the 177013th page of the website) of a certain hentai manga on some well-known adult manga site.
This manga's story ends in such a way that people feel sad. Some people even go to great lengths to make their own versions of the manga. Which is quite interesting as the main story have been trolled a lot on the internet.
It could also be because people like to shock you with things they find interesting. Just like Boku No Pico manga it was trolled a lot and out of curiosity people started to read the manga.
The other thing is You-tube also plays a big role in this as some youtubers after reading this manga began to give their reviews about this manga which sparked the curiosity among certain readers.
Many readers love to dive deep into the dark side of things. It is an excellent choice for readers who are interested in reading about the dark side of life. It is not the same for all viewers and readers.
