Masked Bravery will contain LGBTQIA+ content. More specifically, an aroace protagonist (Judas), an unrevealed demi-boy character, an agender vendor, with a couple other examples.

Undertale itself has LGBTQIA+ content, the "morally correct" route literally requiring you to get together multiple queer couples.

Happy pride month, and if you are homophobic:

1. You are NOT welcomes here :D!

2. You missed half of Undertale itself!
