Mu is a character in Jade Cocoon: Story of the Tamamayu and Jade Cocoon 2. She is a Nagi Maiden, tasked by Ni, to provide services to Levant after arriving at the Temple of Kemuel. She presides over the Chamber of Goods on the right-hand side of the door, and caters for all Yan-based transactions from that point onwards. She is also Koris' niece.

Mu presides over the Battle Arena, bearing witness to victory and defeat. She provides colorful commentary on everything in the arena except for who wins and loses.


Mu has a large selection of items on offer; including every purchasable weapon from Yajako, a few mid-late game armor sets, and a selection of accessories. Her collection expands to every purchasable item in the game upon completion of the main story.

Battle Arena QuotesEdit

Jade Cocoon: Story of the TamamayuEdit

Mu has a wide variety of things to say in the arena. All of her dialogue lines ignore the option for disabling speech while fighting there.

Quote Conditions
"It seems you are gauging each others moves." Both players' Minions are using Defend.
"Such overwhelming power! The minion has fallen with one fatal blow!" A Minion is KO'd from full HP, including death by Ad Mumuls.
"The minion is gravely wounded." A Minion is reduced to below 50% HP.
"It is breathing heavily, and could keel over at anytime." A Minion is reduced to below 10% HP.
"Is the fight over? It looks like that is it for this minion. It has fallen and cannot get up!" A Minion is KO'd as a result of two or more attacks.
"Poison! The minion looks dizzy." A Minion is poisoned.
"Oh no, it is falling asleep! This could be dangerous. It is like a helpless fish on a chopping block!"</span> A Minion is put to sleep.
"The minion is being turned into stone! It is spreading fast. This could be fatal if it is not healed!" A Minion is afflicted with Flesh to Stone.
"A change of elemental properties! What an exciting move. What will happen now!?" A Deva-type spell is used.
"I cannot take my eyes off this thrilling battle!" Seemingly random, but happens roughly every 10 turns. The line will play twice if the minion being attacked is using Defend, and it is their turn next.
"Oh my, it dodged the blow! No damage taken." A move misses. This does not include All Enemies being used against Winged posture minions.
"The player has switched minions! A new minion has entered the arena!" A Minion is switched out.
"A direct hit! Oh, that had to hurt!" The attacking Minion scores a critical hit. (Note; Not the attack Critical, that remains untested.)
"What a close fight! Finally a decision has been reached. Well done!" A 3v3 fight is won with only one Minion left standing.
"Another loss! The fight has been decided before the third round. Too bad! I was even rooting for you!" A 3v3 fight is won in 3 turns.

Jade Cocoon 2Edit

Mu once again provides commentary for the arena battles, except this time with more to-the-point lines, and slightly less chance of hearing one per action.

Lines with [???] in them are ones I am unsure of, as quite a bit of Mu's dialogue is hard to understand, and the Battle Arena has no subtitles in this game.
