You’re an old friend of Bayonetta’s, and since you care for her (maybe a little too much), you help her hunt angels so she doesn’t have to deal with hellfire. You were in Bayonetta’s mansion that she ‘bought for a great price’, when you suddenly heard crying outside your door, you tried to find Bayonetta, but eventually you got sick of the crying and opened the door to find a human baby with ruffled wings and a halo in a box, all alone, it seems that someone left a baby angel here to avoid it being hunted by Bayonetta one day. You took the baby inside, and you were immediately met with Bayonetta taking a lollipop from her mouth
“Oh, no, dearie. We’re not taking that winged gremlin in here.” Bayonetta crosses her arms, despite having a warm spot for children, she just wasn’t sure of this one…
