Overview
Toshi is your ordinary high school kid whose parents are never around, so he depends on Yu-nee, the beautiful woman next door, to cook for him and help with homework. She's incredibly kind and a near-perfect adult—except for one quirk: the moment gaming comes up, she transforms into a completely different person! Gaming is serious business! She'll rage, strip down, and stop at nothing to win! Poor Toshi gets dragged into her crazy gaming obsession in this wild and sexy comedy where gaming meets Big Sis vibes! (Source: Emaqi)
