hood, top, awning, cover, (kokuji)
袰 centers on a covering that hangs or extends over something: a hood, an awning, or a top cover. The meanings all describe a protective or sheltering layer.
袰 is a kokuji (a kanji created in Japan) that combines 母 (mother) and 衣 (clothing) to suggest a mother-like protective covering, such as a hood or awning.
A mother (母) wraps her child in clothing (衣) like a protective hood or awning. Picture a mother's embrace forming a safe cover over her child.
For ほろ, imagine a hero (ヒーロー, hīrō) wearing a hooded cape: the 'horo' sound in hero cues ほろ, and the cape is the covering.
