Meaning of 成叶 in ランドセル姿の成叶がいるんだぞ


I can't understand the meaning of 成叶 in that sentence:

> ランドセル姿の成叶がいるんだぞ!?




landoseru sugata no 成叶 ga irun da zo!? ...that is almost certainly some
person's name. because japanese kanji have so many readings, it's not easy to
know what the name might be, unless this is from a known manga/anime/novel
with a known character list... but assuming that IS someone's name, this
sentence is pretty straightforward:

There's 成叶 ... wearing a child's school bag!?

or possibly: 成叶 will be there wearing a child's school bag, you know!?

(back pack, school bag, ruck sack, etc)

with no other context it's hard to know how exactly the sentence is meant to
be conveyed.

doing a quick search, I'm pretty sure those 2 kanji are the name "Kanari" or
possibly "Naruka", if they are a name at all. If not I have no idea what word
they might be... Context would help a little.
