With the knowledge he learned from Roxanne, common video game strategy, and skill settings, Michio develops a method to efficiently make money.
I could never imagine this happening 
in the world I came from.
In meiner alten Welt hätte ich mir so etwas
nicht einmal erträumen können.
Cuando estaba en mi mundo, jamás
habría imaginado una situación así.
Cuando estaba en mi mundo, jamás
habría imaginado una situación así.
Je n’aurais jamais imaginé connaître ça
dans un autre monde.
Non avrei neanche mai potuto immaginarla
una cosa del genere, nel mondo da cui provengo.
No mundo de onde vim, eu jamais imaginaria
que algo assim poderia acontecer.
