名前って、ふたつ以上の鐘の音

A French-Japanese man, Julien, has two family names: "Condom" on his father's side and "Tanaka" on his mother's side. Now a university student, he still struggles to come to terms with his unfortunate surname and avoids forming relationships. Something in him starts to change when he encounters the Omata siblings, who by coincidence, share the same problem.
