Masamune recieves a letter with the words "Pig's Foot" written on it and realizes someone knows about his past. Masamune tries to find the person who sent the letter, and it ends up being someone rather surprising.
If Adagaki Aki finds out who I am,
،إن عرفت أداغاكي أكي من أكون
Falls Adagaki Aki dahinterkommt,
wer ich in Wahrheit bin,
Si Aki Adagaki se entera de quién soy,
Si Aki Adagaki se entera de quién soy,
Si mon identité est dévoilée
à Aki Adagaki…
Se Adagaki Aki dovesse scoprire chi sono,
Se a Adagaki Aki 
descobrir quem eu sou,
Если Аки Адагаки узнает, кто я такой...
