The next day,
Carrying Esdeath on his back, he travels to the Empire to find some material. Even though she can walk, she likes it when he carries her. The journey cost only an hour since it is not that far from his place.
When he arrives in the city, despite the fact that he is in the past, the place isn't that much different from the anime. The only thing he can see is that the bar that Tatsumi went to meet Leone isn't built yet.
Nonetheless, he still arrives at the market to buy all the ingredients and clothes with the money he received from the bandit. He also buys ice cream for Esdeath. Looking at her smile while eating, he is truly happy.
Seeing a crowd gathering peak his curiosity, so he walks to them to check the sutution. What greeted him is the sight of a woman's dead body tied to a cross. Her body is tortured with a lot of scars. He can even smell the scent of sex.
A fat nobleman stood in the middle giving a speech. "As you can see, a peasant dared to try to rob my house, so I made her an example for all. This is a warning to all those that dare to define me."
Hearing his words, anger can be seen in Katsu's eyes. How can she rob a noble house that has a guard trained in combat? Even Esdeath thinks he is lying, but those commoners didn't talk back, even agreeing with him. Maybe they are her family or neighbors that know her but are afraid of his authority.
"Esdeath, this is my first lesson for you. Try not to trample the innocent. If the only choice is to kill them to save someone you want to protect, then you can do it, but never kill them for fun or trample on their dignity. " Silently converting his message to Esdeath,
He turns back and walks away, but not before taking out a knife from his bag and throwing it into the sky. Of course, no one sees his quick action except Esdeath and a certain blond girl hiding on the rooftop, looking at the crowd.
The knife dropped from the sky, hitting the noble's head, dropping him dead. Screams and shouts can be heard after Katsu leaves.
The blond girl sees Katsu leaving. She silently follows him, jumping over from building to building, but as she is jumping, she suddenly stops when she sees him now standing in front of her.
Knowing the girl is following him, he climbs the building to meet her. From his guess, this is the past Leone, seeing how it resembles her future.
She took out a small bag of coins and gave it to him, "Thank you for avenging her. She took my place and I can't do anything but watch her being taken."
"How about I take this as a recruitment fee to train you, so the next time you have the ability to fight back."
She hesitates a little when she hears Katsu's offer, but at this chaotic world she have to become strong so she accepts it with firm determination.
"Welcome to the family. I am Katsu. Say hi to your sister Esdeath, "he chuckles before pulling Esdeath down. The two look at each other. He doesn't know why, but he can feel the atmosphere is a bit off and sparks are flying out of their eyes, clashing against each other. After a solid 5 minutes, Leone finally said her name.
"Okay, I will just assume that we are already friends and let go then", he said before carrying Leone with Esdeath jumping on his back, rushing back home before those guards lock the place down.
After arriving home, he also introduced the invisible spirit, Dark Magic Girl. She appears in her human form with a cute introduction. Her appearance clicks in Esdeath's mind why she always feels another person is watching her.
The two girls didn't dislike her and even greeted her back. He doesn't know if it is the dark magician girl's charm or her natural ability to befriend people. She quickly becomes the older sister of the group that everyone likes.
Of course, he introduces her for a reason: to teach magic. From what he learns, he can gain a monster card skill if he consumes it, but what about teaching it? When he uses the monster card Vorse Raider for the last time, when it ejects from him, he can't do the techniques he used to do, but he becomes more proficent in his axe bearer weapon, and when he asks if the Dark Magician Girl can teach magic to people, she confirms that everyone can learn magic, but how much depends on their ability.
When she explains how to use it, Katsu understands and takes notes, but Leone becomes brain-dead.She is teaching about mana, which is the life force energy that consists of everyone and every living thing. Different people have different amount of mana. Is it like stamina but also different? Where stamina is a measure of your physical reserve, mana is your mental reserve. Mana isn't used for casting spells but to fuel the spell's ability to work. That is, if you have an idea in your head, mana provides you with the ability to express that in play and turn it into reality because some spells are too strong and need a place to channel them and gather the mana. If the container isn't strong enough, the spell will be broken. That's why she needs a wand and this book. The wand is to channel the spell, and the book holds the theory of the spell. You can do the spell by hand, but people tend to use a wand because it is easy to chant the spell and gather power. (Different worlds have different concepts. Okay, when you meet other worlds in the future, that's when you will explode and many plot holes will be created, but I still write this for fun and this is my story, so any disagreement can go fuck itself. Of course, if you can give any good suggestions, I can edit them. Also, believe me, when I tell you, it will get complicated.)
At this point, Leone is lying dead already, while Katsu has a light headache. Esdeath tries to do it and succeeds in creating a small ice shard, but that causes her to become a bit weak. Esdeath succeeded in her first attempt, much to the surprise of the Black Magic Girl, who received a bit of a stunt but still continue to gave Esdeath advice to perfect her magic.
After three more hours of the session, he could finally do simple spells by hand, mostly boost spells, but it was already a game-changer in battle while Leone didn't learn a thing.
