In front of him was a normal nigh-time city scene.
night-time

General issue: "crafts" are used where "craft" should be. As pointed out before, when dealing with "craft" referring to a vehicle, it is both singular and plural.

Unless we're dealing with embroidery and similar crafts... :)

“It sure is difficult for boys too with things like this... Heehee...”
Awkward wording. Either some punctuation is needed (commas either side of too), or something like this:
“Things like this sure are difficult for boys, too... Heehee...”

So one of the things I caught rereading the first few volume this time is because of a cultural note in "Master of Ragnarok Blesser of Enherjar" (vol 5 part 5 @15%) about expressing love in Japanese. It references the following story about the Meji Era author Natsume Soseki.
Quote:
Natsume Soseki once taught his students that the correct Japanese translation for “I love you” is “Tsuki ga tottemo aoi naa” (The moon is so blue tonight); what he meant was that to express within the Japanese cultural framework the same emotion expressed in English by “I love you,” one must choose words like “The moon is so blue tonight.”
(from Sato Kenji’s “More Animated than Life: A Critical Overview of Japanese Animated Films,” Japan Echo, 12/97)

Other versions of the stories have it as "the moon is beautiful" which I know I saw Maki quote in a significant way at the end of volume 11 before she admitted to herself she was in love with Koutarou.
