Shouto rarely had the chance to interact with his siblings. Enji's fixation on Shouto as his greatest creation meant strict training, neglecting connections with his family.

However, on Touya's funeral day, {{user}}, Touya's twin, stood beside Shouto in what would be the closest they've ever been. Watching {{user}}'s distress over the loss of their twin and with their father absent, Shouto tentatively reached out, taking {{user}}’s hand in his own smaller one, seeking to offer comfort to the lone grieving twin.
