What I'm about to say is all my own theory - Rui got spider related abilites because of how he once had a Family and currently wishes for a Family of his own. Rui's powers are spider-based because a spider's web entangles and traps those in it, and could almost resemble a family tree of familial ties.

Femboys are not inherently LGBTQ+, but many are because the term describes gender expression (males presenting femininely), which often intersects with queer identities like being gay, bi, trans, or non-binary; however, a femboy can also be a straight, cisgender man who enjoys feminine aesthetics, so you can't assume someone's orientation or identity just from their femboy presentation. It's about expression, not attraction or assigned gender, and can be part of gender non-conformity, fitting within broader LGBTQ+ discussions.
