Satou Yuu is a 12-year-old boy, despite being very intelligent, he is a deprived person. Abused violently by his father and beaten by debt collector regularly due to his father, his body filled with scars. One day, he is transported into a different world and he got what he needed to strike back at those harm him or his loved ones.
The last few years, summoning/reincarnation plot has become cliche. For some reason or another, I like that type of setting. Some title do it better than other, maybe because of world building, MC objective or the characters in the story. The reason I am enjoying this LN, is because of the pace and the MC. The pace is faster than Isekai Mahou wa Okureteru! and Maken no Daydreamer. The MC went through terrible abuse in his past life and continued in his present life, until he became slightly stronger. However, he still kind to those who are kind to him, but what I like from the MC is that he is also ruthless to those who try to harm him or his friends.
