Introns can also be unlocked using Phoxene Plumules, the premium currency in Duet Night Abyss. Phoxene Plumules can be purchased directly from the 'Shop'.
Tips! | You cannot purchase Thoughts or use Phoxene Plumules to unlock Introns for the Main Character. Their Thoughts can only be obtained by progressing through the Main Story. |

Once you have enough 'Thoughts' or 'Phoxene Plumules,' head to the Armoury by pressing 'C' on your keyboard or (Right D-Pad + X) on your controller. Then select Character → Intron → Choose Intron Lv. → Unlock.
