An anon asked for the font for the Free! title logo; it seems like a stylized San Serif that they either created/modeled after/paid for etc., but here are three similar ones via a quick look in dafonts if anyone else wants to know.
here (focus on r, similar letters, wider than below font for the edit of "e")
here (focus on r, already slanted typeface)
and here! (focus on e)
and for a kind of cool-looking but similar "f," you can try techno hideo, though it might clash with the other fonts (haven't tried putting them together; solely recommending it cause it looks cool).
Also, the question mark looks like a really stylized Mincho.
