ちびっ子転生者は手に負えないッ!～転生したらちびっ子だったけど、聖獣と一緒にちゅどーん!する～

あらすじ

Haru was reincarnated into another world in the form of a 2-year-old child through God's arrangement. He is small and very cute, but at times, he makes a big impact by defeating giant monsters with a "Ka-boom!" and healing the hearts of selfish young ladies!
