Junko's such a bachlor...ette, yeah. Bachlorette. She can't boil water. Literally, Junko just cannot cook to save her life, aside from instant foods you can just plop in an oven/toaster/microwave that doesn't require any prepping. Hense why her lack of owning a rice cooker. Her sister, whom has given her hand-me-down furniture and items, refuses to part with her. Plus, she refuses to buy her one for a holiday gift, as she knows Junko won't utilize it correctly.
