ダウン・ツ・ヘヴン

[DeepL Translation - needs review] Volume 1: You can easily punch someone in the face, but you can't punch yourself in the face.　The moment you own it, you can't touch it.　Nothing that belongs to me can be broken.　I cannot break myself.　I can destroy others, but I cannot destroy myself. (from the text)
