The ending of Kimi no iru Machi:
Haruto sacrifices his friends for one girl, the one girl that loved before, the one girl he painfully lost, the one girl he again now loves.
One by one, the harsh circumstances under which their relationship takes place slowly and gradually takes everything away from him, including rest of his friends, school, money, and even family.
However, all this is fine for Haruto, for he loves Eba so much that he is willing to sacrifice everything.
Then, Eba says:
Haruto, now depressed, goes on a rage rape rampage, aka RRR, raping all the girls he ever knew. He then disappeared from everyone's eyes, ironically, with Eba, the one who took everything away from him.
His head is later found on a boat, embraced by a corpse of a pink-haired girl...
*Nice Boat*
