Tensei Gyaru Yuusha to Toraware no Hime: Morahara Yoshi Jikka wo Kouryaku Seyo

Yuka, a former gyaru and office lady in her 40s, is hit by a truck. When she regains consciousness, she's reincarnated as a vibrant 19-year-old girl!? And with a handsome husband! Her perfect second life begins now...or not. It turns out she's living in a hellish house with an abusive husband and a bullying mother-in-law...? Use your gyaru power to completely defeat the abusers in a refreshingly new way! A new kind of in-law battle! (Source: Shogakukan, translated)
