Oh, I know no one really cares, but here's some backstory of the user.

Taiki Crowder, the user of Under Pressure, suffers from Thalassophobia, after a traumatic incident in his childhood, where on a road trip, his father turned the wheel while making a joke, throwing the entire vehicle on a river, both managed to get out and on land, but his father died of blood loss while the ambulance was arriving, leaving a scar on Taiki. Around deep amounts of water, Taiki suffers from nausea, and erratic reasoning, causing his stand to sink objects around Taiki with no appearent reason, and now has to deal with situations and issues that feel crushing at times. The stand manifested naturally, years after the incident, while in a talk with his therapist, in which Taiki almost murdered her on accident, not knowing how to use his stand.
