SHIKKAKU KARA HAJIMERU NARIAGARI MADOU SHIDOU!

Let me tell you the story of Arcs Reytheft
A great feudal lord’s disgraced eldest son
Because he was weak, he his family left
And so he strives to become the strongest one

For you see, Arcs was once a Japanese man
And got sent to this world as soon as he died
His father wanted to have Arc inherit his land
But in terms of magic, he was disqualified

The background is set, and Arc’s goal draws near
Get back at the people who mocked his weak skills
Whether by training or cheats? That part is unclear
But who cares? It’s time for some self-insert thrills
