Throughout the series, Ryu Kurokage weaves together themes of grief, loss, and the power of human connection. The angels in "100 Angels" serve as a symbol of the love and kindness that transcends even death. They represent the emotional bonds that we form with others and the impact that our actions can have on those around us.
The manga also explores the complexities of childhood emotions, as Iori navigates the challenges of growing up without his mother. His journey is both heart-wrenching and hopeful, as he learns to cope with his emotions and find a way to heal.
As the story unfolds, Iori learns that these angels are, in fact, manifestations of the kindness and love that his mother had accumulated during her lifetime. With Sakura's help, Iori sets out to uncover the truth behind the angels and the mysterious powers they possess.
