ゲーム世界のモブ悪役に転生したのでラスボスを目指してみた～なぜか歴代最高の名君と崇められているんですが、誰か理由を教えてください！～

The last boss of the game Altena Fantasia... ...Isn't me. I was reincarnated as one of his underling mob villains. Determined to take the place of the infamous last boss, I resolved to liven up the game as a true villain. But for some reason, all my misdeeds end up being praised, and my reputation soars...?! How did it come to this? Somebody, please tell me!
