Akinobu Mon'yo Tokusei: Oni no Wanryoku (Akinobu Bloodline Trait: Oni’s Strength)

Through generations of magically enhancing their physicality, the Akinobu clan has gained a moniker of super strength and athleticism.
You gain the following benefits:

You can effectively wield any weapon with the two-handed property in one hand. Although if you are small, you still suffer the penalties of wielding heavy weapons

you can dual wield two handed weapons in each hand, however your off hand weapon does not gain a bonus to damage from your strength modifier, even if you get the two weapon fighting fighting style or any similar feature

This feat doesn’t give you the benefits of the dual wielder feat.
