Lethren: A Living Grave Within The Abyss

After mysteriously falling into another world, second-year university students awakened the ability to use elemental magic. The tech from their old world became nothing but obsolete. Without a digital encyclopedia to rely on, they needed to figure out how to survive in this unknown place. Naturally, the charismatic Noel became one of the main leaders alongside Emely, their young, beautiful professor. And together, they’d keep the peace between different groups. Almost indifferent to the situation, the protagonist was inclined toward a wait-and-see approach; if they became miserable, he would be the tyrant they so desperately needed. Note: I don't expect that you have read my other work; you don't need to. But if you have read it, then it's kinda like another route story with the main focus not being romance.
