Now back in Edo, Gintoki doesn't know how to face his old friends, and so he decides to try and avoid running into any of them. However, that won't be easy.
it must be a case where the mankind-protecting 
protag despairs in our foolishness
لا بدّ أنّها حالة ييأس فيها البطل حامي البشرية من حماقتنا

o protagonista que protegeu
a humanidade até agora
