I thought this too when I first saw the name but then I considered why she would be using the old character in the first place.

the reason why 1, 2, 3 have old characters is because they look like this

一　二　三

can you imagine using those on money and in legal documents? It is too easy to alter, etc, so they used older very complex characters to make it more standard and failsafe. Characters for other numbers, however, aren't as similar.　4 and 5, for example, don't look any other number so the precautions to take with them aren't the same as with 1, 2, and 3.

Oh, I see. Thanks for the information
So, we have to wait for Seiteki Healing ~ sono juu~ to see the old Kanji again
