What do these numbers mean and why do these characters have these specific
numbers?




The roman numeral represents the kakugane's serial number. There are only 100
Kakugane, from I (one) to C (one hundred). There are 29 known kakugane that
are used (in Japan) in the series.

Kazuki's "LXX" kakugane is... special.
