In order to unlock every skin, we have to beat the game twice ON THE SAME SAVE FILE. Because of that, I suggest completing the game as follows:
- during our first playthrough, choose ,,Break the iron code, stay loyal to Kuro''
- after finishing the game, on New Game Plus, choose ,,Obey the iron code, forsake Kuro''.

This skin is available from the start of the game.

We can obtain this skin after finishing the game.

We can obtain this skin after completing the Gauntlet of Strength: Severance. In order to unlock this gauntlet, we have to defeat the following bosses:
- Isshin, The Sword Saint

We can obtain this skin after completing the Gauntlet of Strength: Shura. In order to unlock this gauntlet, we have to defeat the following bosses:
- Isshin Ashina
- Demon of Hatred
- Owl (Father)

***********************************************************************************
FIRST PLAYTHROUGH - STAYING LOYAL TO KURO:
***********************************************************************************
Owl (Father) - the hardest one to get to (and the most missable). Remember to complete the following points BEFORE FIGHTING the final boss of The Fountainhead Palace The Divine Dragon. After defeating Great Shinobi Owl :

1. Go down and talk to Kuro;
2. Go behind the wall Kuro is facing and eavesdrop on Kuro and Emma;
3. Rest by the idol and confront Emma (she can be found upstairs);
4. Talk to her, agree to her plan and talk to her further until she gives you Tomoe's Note;
5. Teleport to the ,,Old Grave'' idol in ,,Ashina Castle'' area;
6. Go through the gates on the left, where you will find Emma standing in front of the graves;
7. Talk to her;
8. Teleport to Dilapidated Temple;
9. Go behind the temple and eavesdrop on Emma and the Sculptor;
10. Confront Emma to reveal her secret (you will receive Father's Bell Charm) ;
11. Use it to access The Second Memory (WARNING! Activating the second memory will replace some of the areas from The First Memory (the one with Lady Butterfly). If you still want to clear the First Memory, do so before activating Father's Bell Charm, as after that there will be no possibility to access The First Memory);
12. Progress through the area until you come across Lady Butterfly arena, but instead of her, there will be Owl (Father) waiting to battle you.

Isshin, the Sword Saint - He can be found at the end of the game (after defeating The Divine Dragon), in Ashina Reservoir, where we fought Genichiro Ashina and lost our arm at the beginning of the game.
