I use Yugioh to battle the multiverse

(Infodump)

The two new members Gilberda and Cassandra are quite obedient maybe because of seeing his strength, but when choosing an outfit to wear Gilberda wants to be a maid for some reason despite her belligerent personality and Cassandra cloth well she has four arms so normal clothes won't fit her.

He doesn't know how to make cloth so he has to find a tailor before coming back with them. The journey is easy since no one bothers him at this hour.

When he comes back, morning comes with all of his students waking up greeting the new two members.

The first thing that Merraid wants to do when meeting them is introducing them to the new world (she tried to convince becoming homosexual) so Katsu has to stop her before she corrupted anyone. Loris and Meela have already become a victim, but they still blush when seeing handsome boys so at least they are not completely corrupted.

Cassandra is happy that everyone in the group doesn't care about her four arms and treated her normally while Gilberda fell uncomfortable and comfortable at the same time with everyone respect her strength not feeling scared at all like her parents.

Cassandra training is helping her master all weapons having four arms is quite convenient in battle and training since she can train different weapons at the same time.

Gilberda training is similar to all of the hand to hand combat he has given to the children but she has more advantages because of her immense superhuman strength

Those happy days went by in a flash everyday Katsu teach them all of the knowledge and skill he has for them. He never really force them to train too much and always help them even Dark magician girl put a lot of effort to teach them magic but not everyone has talent only Merraid can activate magic to enhance herself like Katsu while Balluck and Esdeath are the only two who can cast spell the rest give up knowing they can't even understand what Dark magician girl is saying.

By helping them meet each other he already changed the past a lot and became the teacher they respect and love. So hearing the news that he will be gone all of them have a breakdown and try to keep him even Guy a bastard doesn't want him to go.

Despite that, he still has to go back so he tells them the truth about his arrival. " Don't worry we will all meet again in the future so live well, I don't want to visit anyone grave when I come back" he chuckles taking out all of their destiny weapons

Waving goodbye at them as the last day end. His body slowly turns into particles and vanishes into thin air
