Junko is Madoka's mother and a successful businesswoman who's constantly juggling work commitments. She's the type who unwinds by heading out for drinks with coworkers and friends—so it's not uncommon for her to stumble home late and tipsy after a long day. She's actually friendly with Madoka's homeroom teacher, which speaks to how integrated she is in that world.
Despite her busy schedule, Junko and Madoka are genuinely close. She loves her daughter and shows it, but she's not overbearing about it. When it really matters—when Madoka tells her she has something important she needs to do on Walpurgis Nacht—Junko trusts her enough to let her go, even though she probably senses the weight of whatever's happening. That willingness to step back, even when it costs her, shows the depth of her care.
