"I have to do this as soon as possible I won't allow Y/n to disappear from my side." . . . . .
(Picture Processing)
When Tanjiro heard about your situation, he was not his cousin and continued with his experiment, but deep inside Tanjiro could hardly bear what the Ordinary demon told him about your situation.
Tanjiro put the tube he was holding in a container and he took an empty tube and put Douma Ganon's blood in it which was also Giyuu's when Tanjiro transferred their blood into a tube Tanjiro put it in edge where the blood of the twin demons Yoriichi and Michikatsu.
When Tanjiro put it to the side, he took the book that Miku had been hiding from him for a long time and he broke a page in it where it says how to become immortal with the blue spider Lily.
As Tanjiro read it, his blood boiled with anger now because if Miku would just give it to him right away, he would be immortal now.
"How is he feeling Today?" Tanjiro asked the ordinary demon while his red eyes were focused on the book he was holding.
"Lord Tanjiro his body is weak now and he is a bit pale." The ordinary demon answered him here that Tanjiro realized that you need sunlight to get vitamin C from your body.
"Yes Lord Tanjiro." This was his response before he left his laboratory and now Tanjiro will be the only one in his laboratory who is thinking of visiting Sabito and your other companions who he considers your rival.
As he closes the book he was holding, he stared at the flower on his right side, the blue spider Lily. Tanjiro thought again if his decision was right.
'Was the decision I chose correct? I choose to make Y/n immortal? In exchange for my being the prefect being in this entire World?'
Tanjiro thought to himself as he stared at the blue spider Lily he reached out his right hand and Tanjiro held the leaf of the blue spider Lily as he wondered if his decision he chose was right.
Until he remembered what Sabito said to him then they talked.
'Y/n will never love you remember that.'
"No that's not true Y/n loves me so much." Tanjiro whispered to himself while his hand was shaking in fear, this was the first time he felt fear in himself.
Fear that he will never be able to accept to himself that Tanjiro doesn't want you to not love him either because he loves you so much even if you think that he is a monster in your eyes but Tanjiro loving you as a demon king is can never be changed.
But what Sabito said to him always haunted his thoughts while Tanjiro felt his blood run cold down his whole body and his nerves that he was shaking and he didn't know how he could calm himself down because He thinks what if it's true What Sabito told him what if you can't really love him like he loves you.
