Luciel registers with the Adventurers' Guild and begins martial arts training with chief instructor Brod. As part of that training, he is forced to drink Substance X, a mysterious and disgusting beverage that confers special powers like a cheat item.
The bitter, tangy mix with spicy 
and sour flavors ravaging my mouth...
الخليط المرّ واللّاذع مع النّكهتين الحارّة
...والحامضة يدمِّر فمي
Un sapore amaro e acre,
che mischia assieme anche il piccante e l'acido
Os sabores amargo, picante e azedo
fortes estão acabando com a minha boca.
а горько-остро-кислый вкус
не оставляет жертве ни шанса…
