Reborn Into The Seven Deadly Sins World

After Leo returned home he was badly scolded by Mary for missing for an entire day, being covered in mud and having tore clothes, also, his puppy eyes didn't work this time.

'Tsk, why I'm in a child's body if I can't take advantage of it...Sigh. No matters, I asked the old man to train me and he agreed immediately, being the muscle brain he is, he said: "Every man should be proud of his body and become a warrior!"...well, this is an era where you have to train your body to bring the bread home.'

'But the most important thing for me now is my darkness, I can feel it's like a part of my body, but I can't make it disappear and appear at will like the Demons, it's like it's 'stuck' here...I can manipulate it at will with a bit of effort, but today I will start the training to use darkness at 100% power, with my immagination of a modern man of Earth, I will use the darkness in a way even Demons will be jealous.' These is the list of things I should try with my darkness:

-Can I stretch it? Will it broke if I stretch it? Can I split it? How much? Can I change it's colour? How far from my body can it go? Can I change it's attribute? Will it grow as I become older? How much can I condense and press it togheter? Can I mix it with magic? Can I turn it invisible?'

'But the very question is: What will happen If I use [Absorption] on the darkness insted of my body? Will it grow or the effect will nullify? Man, that's so intriguing my body is itching for this.'
