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.
I might be able to find out 
whether she's Unknown X or not.
.قد أتمكّن من معرفة ما إذا كانت المجهول إكس أم لا
Vielleicht finde ich so raus,
ob sie der Unbekannte X ist.
Así podría averiguar
si es Misterioso X o no.
Así podría averiguar
si es Misterioso X o no.
Je pourrai découvrir si c’est elle
qui se cache derrière tout ça.
Potrei scoprire se X è davvero lei oppure no.
Talvez eu descubra se 
ela é a Pessoa X ou não.
Так я смогу узнать, 
она ли тот неизвестный.
