The story is about a girl named Yuu and a boy named Ken.
Only in Yuu's case she is the opposite of Tama-chan. She's too tall and mature looking for her age. A 12 year old first year middle school bombshell.
She gets scared when older guys try to hit on her.
But just like Tama-chan she is an Otaku. She also practices kendo with Ken.
Only in her case she hates Kendo. Why? She's bad at it.
Ken looks like a mini Kojiro-sensei who still has his youth. An elementary brat.
Nana is Yuu's loli best friend in middle school.
Apparently Yuu is attached to her little friends. Quite a contrast to Tama-chan who only had Yuuji in the beginning.
Though Yuu tries to escape Kendo. Destiny is out to get her.
