When I write fanfiction I find it rather unsatisfactory that the five main characters don't have proper names. So I made up some for them, which I'm going to use from now on (you can find them already in my fanfiction 'The Summer Festival').

Here they are:

AzureFang – Sayuri (meaning 'lily', but also the main character from 'Memoirs of a Geisha', who is said to have 'water in her soul')

BreezeDancer – Ama ('amai' means 'sweet'. and isn't she just sweet?)

CrimsonFist – Mamoru (meaning 'to protect', which I find very befitting)

MidnightBlade – Masamune (the name of the sword type which Sephiroth in FF7 uses, and isn't MB a great sword wielder?)

ScarletBlaze – Akio (meaning 'autumn king', as his fiery Jutsus are like leaves in the wind)

It is probably wishful thinking, but I hope you like and accept these names and I'd be very happy if you used them.
