I'm far from done.

Kou Ichinomiya has achieved everything life has thrown at him living by the words his father told him, "Never be indebted to anyone", this comes back to bite him when he is saved from drowning by a mysterious girl named Nino. Kou being indebted to Nino is desperate to return the favour with Nino asking for him to love her, so begins Kou's new life under the bridge where he lives with a number of other strange people.
The theme of this one is of Denpa-san, a term used to describe people who feel dissociated from the people around them often engaging in wild fantasies, delusions, strong beliefs and engaging in strange speech and actions which easily describe the bizarre characters in this anime.
The anime uses Kou as audience surrogate to really get to grips with each character and their behaviour but there's also an underlying feeling of what made them that way to begin with, shown perfectly when Nino appears in an elegant evening dress for a date with Kou despite looking like she never even laid eyes on a dress like that before let alone wear one. It's definitely worth watching to find out.
I don't remember there being a dub so I've no opinion on it.
Final Verdict: A bizarre anime that makes you question things in a good way, it's worth the investment.
