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'm so stressed out, my tummy hurts...
...أنا متوتّرٌ لدرجة أنّ معدتي تؤلمني
Vor lauter Stress
hab ich schon Bauchaua …
Estoy tan estresado
que me duele la pancita…
Estoy tan estresado
que me hace pupa la tripita…
Tout ce stress
me donne mal au bide…
Tutto questo stress mi fa male al pancino...
Estou tão nervoso que
 minha barriga dói...
У меня такой стресс, животик болит...
