Journey of Desires

- Done! Sister come here, I finally finished writing the spell, we can go!

In a fairly spacious building there was an office filled with various books, in it there was a tall blue-haired man, and he was calling his sister who looked very much like him, but her height was quite ordinary for a girl.

- Coming, coming!

- Please check, I think that everything was done correctly, well, at least over the past couple of years I have not made a single mistake in the spells.

The girl approached Brother and with a sharp jerk took a couple of sheets of paper from his hands, and quickly checked the contents, nodded her head affirmatively, after which she headed for the exit of the building.

- Let's go! Let Merlin check, if she gives the go-ahead for this spell of interworld teleportation then I will be calm.

This time the same man was sitting in a different room, it was a tavern, where a short guy with wheat-colored hair was sitting at a round table opposite him.

- Captain, I'll miss you...

- Ban, you decided to go on a journey yourself, there's no need to regret your choice, or did you decide to change your mind?

The reaction to this seemingly simple question was too strong, the tall man didn't just say "No!", but literally stood up and, as if in a panic, almost shouted this word, and then, sitting back, continued.

- There hasn't been much interesting in the last four years, actually... I didn't tell you, but after the purgatory in which we almost went crazy, I got hooked on constant battles, peacetime is nice, of course, but without adrenaline or constant learning of something new, it's terribly difficult for me.

- Ban...

- Captain, I haven't felt joy in the last 2 years, except for the moments when you were making pizza, and yesterday when I was able to finish the spell, don't talk me out of it.

- No, I'm not talking about that, your tea spilled, I understand that you hardly feel pain, but the sensation of touching hasn't gone away.

Ban immediately let out an annoyed cry, after which he went to the restroom to wipe off the stain, after all, the tea was with honey and although not much, it could ruin clothes and cause quite unpleasant sensations.

While he was in another room, Meliodas was approached by Ban's sister, who just came up at the moment when her brother got up from the table.

- Mmm, I hope he gets better.

- 3 years ago, everything was fine with him, and until today we rarely saw each other, can you tell me more?

- In short, after defeating the demon king, he gradually lost more and more... how can I describe it, his mood? Like an avid card player who was denied access to any gambling, he tries to occupy himself with something else, but it doesn't work. There haven't been any serious battles for a long time, and we've already explored the whole world together, we even traveled around villages, and there was literally nothing there except houses and residents.

- I see, and then?

- Well, when we finally finished with our tourism, he spent two years increasingly withdrawing into himself until about eleven months ago I got the idea that there could be other worlds. Well, he got fired up with this idea, to create interworld magic, to be honest, I didn't really believe that something so global would work out, but this maniac literally spent half a day every day writing runes.

Meliodas wasn't very talkative today, after all, two of his friends, one of whom is a member of the squad, are going to go into the unknown, and even if everything goes well, he most likely won't know the result. He wanted to ask something else, but at the last moment he changed his mind and only turned to face Kilia, wishing her good luck.

The brother and sister really didn't like farewells, such an action on both of them brought negative feelings not just from childhood but also from past lives, they were born in this life retaining memories from the past, of course, the ways they did it were different, but as a result, two time travelers who lived almost their entire lives almost one to one according to the canon, afraid to violate it and lead to a result that would ruin the good ending. True, in the end, they still realized that such behavior did not make sense, and decided to take everything into their own hands.

They went to purgatory after the ten commandments appeared, having asked for something like this from Merlin, they were still able to get there over time, becoming much stronger, their new powers after hardening in purgatory quite strongly influenced future events. But now it doesn't matter anymore, every action has a consequence, sometimes good actions have bad consequences, sometimes vice versa.

The consequences of the choice to be sent to purgatory made Ban incredibly eager for adrenaline and learning new things, and as luck would have it, studying science or magic did not satisfy his desires at all, tourism with visiting new cities and countries helped quite well, when he got what he needed, he literally turned into a happy child, everything he could do for fun often turned out to be ridiculous or dangerous.

Just like her brother, her sister developed her own small obsession, although it is not difficult to quench her thirst for games in various manifestations, and her too bright reactions to various cute things are often perceived as normal behavior for a girl.

The final result is that they are now standing at their house, having left magic doves with the help of household magic that will bring their friends letters describing the entire situation and where the brother and sister say goodbye to them.

They met Merlin and Meliodas in person, the girl mage had been their mentor for a long time, taught magic and its sections that best suited their innate talents, and Meliodas was a very good friend and before leaving, Ban went to him to say goodbye.

When all the most important things were taken with them, and the farewell letters were ready, the brother and sister prepared for their journey, very worried, Ban looked at their house for the last time.

- I hope we won't be torn apart into atoms, recovering from such a state is quite unpleasant.

- Don't croak!

After which, having moved ten meters away from the house, Ban finally began to mentally reproduce the full magic chain, the brother and sister were covered in strange distortions and disappeared from this world.
