Re:zero anime route unknown if Subaru (Fanmade).In this route from the beginning when he was summoned by witch of envy satella in the kingdom of lugunica.he left the nation or the kingdom of lugunica.because of that he never met any of his friends or lover like in the orignal route and because of that some of them died.He travels nation's to nation's.he explores the fantasy world and because that he got lots of new friends and allies.This route is completely different from all the routes of subaru's.In this route He mastered the return by death ability and he mastered the sin of archbishops book and also trained and become powerful in pshycal abilitys too.In this route he is the most powerful person in this world or dimension and he can defeat Reinhardt too.this route is called unknown if because there are lots of unknown possibilities in his journey.Since he mastered the return by death ability.So,he didn't become crazy.In this route his lover is witch of envy or satella.In this route his personality is:very serious,mature,smart,nice, sometimes kind and understanding.
