Tentou Mushi no Uta
てんとう虫の歌
Seven young brothers and sisters live peacefully, supported by the love of their parents. As a token of gratitude, the children give their parents a trip for their wedding anniversary. This heartfelt gesture leads to a terrible tragedy when their parents are killed in an accident during the journey.
Devastated but determined, the siblings must learn to stand on their own without depending on anyone else. They start a new life of strenuous effort, helping one another with brotherly affection. Their sincere attitude and lively activities gradually win the admiration and encouragement of their community.
