18+ Eroge Fantasy Mitai na Isekai no Mob Murabito ni Tensei shita kedo Sekkaku dakara Harem wo Mezasu

I don't care about another world, magic, or dragons... I just want to win over beautiful girls!

Alex is reincarnated as a "Common Dragon", a dragonkin born without elemental mana, in another world where only dragonkin, descendants of dragons known for their greed, pride, and unwavering devotion to their desires, are capable of using magic.

Despite having a childhood friend, Rina, who is a Lesser Noble Dragon blessed with exceptionally powerful mana, Alex spends his days raising and disciplining her until she grows into a proper young lady. According to the fate awaiting Common Dragons, he should eventually be conscripted into the capital's army. Instead, however, he unexpectedly finds himself enrolled in the prestigious Upper Dragon Academy, a school where the realm's most gifted dragonkin gather, serving as Rina's attendant.

In an academy where only the strong survive, Alex is clearly out of place. Before long, Noble Dragons such as Nasha and the upperclassmen begin to single him out. Yet, one duel after another, he defeats them so thoroughly that he ends up winning them over in his own forceful way!?

"If I win... you'll do anything I say, right?"

Thus begins the academy harem life of Alex, the weakest dragonkin, driven by an insatiable hunger for power (and sex!!).
