""I want to be like that! Not just someone who makes weapons...but someone who can protect everyone. That's the Unbreakable I strive for!!""

Isshin is member no. 6 of the Round Table. She is a Negator with the alias Unbreakable.

Appearance
Isshin's design seems to be based on a traditional Japanese samurai armor called Yoroi. They are also quite bulky in their build, towering over the other members in the Union. They wear the Union logo on their helmet, right above their face.

Isshin's true appearance beneath her armor is unknown, other than her eyes.

Personality
Isshin has been shown to be a quiet and protective person, showing great care for her fellow members. She seems extremely attached to her armor, not wanting to take off her helmet even after being severely wounded in the neck, not making it easier for Nico to check the wound in the process.

Spoil Arc
When Andy and Fuuko join the organization, Andy shoots fingers at each member, but Isshin lets the finger hit them and moves one of their hand's to protect Phil from the other finger. When Apocalypse reveals the new quests, Isshin along with other members take on UMA Burn's quest.

When they captured Spoil, Shen calls for help in stopping Victor and Isshin along with the rest come fight Victor. Isshin slams Victor from behind, making Victor comment that they used only brute strength and if Isshin doesn't fight him, he may let Isshin live.
