As stated in the title help me find something like Mother of learning (Don t need that one japanese manga. I forgot its name though.)
only know of one, and i dont remember anything about it except that it loops! try your luck. http://royalroadl.com/fiction/2612
Watching this thread, I find time-loops(and MC becoming more intelligent because of that) interesting. Well Absolute Choice might work for you, or My Fiance is in Love with My Little Sister(haven't read it but have heard good things about it)
Also a movie with timeloop: Edge of Tomorrow, although you probably know that already. It's based on All You Need Is Kill. A oneshot manga that fits somewhat: Loop A manga that might be the one you mentioned in the OP: Saike Mata Shite mo
Ah well the recommendations are not looking so bright. Anyways, I Thank You all for your time. See you next time.
