Glass Sky (Japanese: 小さなガラスの空, Hepburn: Chiisana Garasu no Sora) is a Japanese manga anthology written and illustrated by Yugi Yamada.

[1] Leroy Douresseaux, writing for Comic Book Bin, felt the manga's storytelling is unusually awkward for Yamada, but praised her "loose, cartoony" drawing style as being very effective in showing "both the external and internal states of the characters".

[2] Briana Lawrence, writing for Mania Entertainment, felt that the range of stories presented made the anthology "sure to please anyone" who reads it.

She especially enjoyed the story about the two older men who reconnect after performing a play together, and the title story, which deals with gay bashing, rare in a boys love manga.

[3] Holly Ellingwood, writing for Active Anime, praised the humour in the anthology, appreciating their "subtle poignancy" and occasionally finding them too short.
