All the Beautiful Girls Want to Save Me

Shinji Saito is an ordinary Japanese high school student. He has a sister, a house, and both parents are dead... I don't know when, Shinji Saito discovered that all kinds of beautiful girls appeared around him... "Ding dong! It is detected that Shinji Saito is very depressed now, please save him!" So Saito Shinji always had a coquettish and cute monitor next to him after class. "Ding dong! It is detected that Shinji Saito is very poor, please save him!" So the arrogant yellow-haired girl with the eldest lady's airs threw the black card on Saito Shinji's face. "Ding dong! It is detected that Shinji Saito is very lonely, please save him!" This time it's the monster sister who turns into a cute kitten, and the earthbound spirit Sanmu girl who has been trapped for thousands of years. "Please let us save you, Saito-kun!"
