Mako Minamino
She's the newest resident of the Tadano household. Ken met her in Alaska when he was taking pictures during the Aurora Borealis, where she was mourning the 3rd anniversary of her high school sweetheart’s death. She was first introduced to Mugi as his new mother, but it is later learned it was a lie and that there were no plans for a wedding. Only being five years older than Mugi, she enjoys suggesting activities with Mugi that Yuu deems inappropriate. Much like Tsukasa, she likes to play games with a sexual twist, like strip Janken, which so far has not lost one game. A running joke is that she dazzles men with her large breasts, which causes various results.
