Shadow Aiko Attacks

Shadow Aiko has four main attacks:

  • Sword Slam: Shadow Aiko will jump into the air and slam both of her swords on you. You cannot parry or block this attack so you either have to back away far enough from the swords’ reach or roll through her attack. Rolling through is a good way to get an opening to punish by doing a Rotation attack, followed by a heavy attack.
  • Sword Flurry: She will do three sword slashes and delay a fourth one. The first three can be blocked, while the last slash is unblockable. She will also not do the fourth slash if you are too far away. Only punish if you manage to roll through her fourth attack.
  • Soul Rain: She will cross her swords and make souls rain on three spots; the middle one is where you are, the one in front is where you’ll land depending on the speed that you are moving at the time of the attack, and another one behind you. You can roll through these without getting hit.
  • Soul Beam: She will stand tall and shoot out a beam of souls towards the direction that she’s facing. She will do this when her health goes past 50% and it is the best time to roll through her and punish her from behind.

After defeating Shadow Aiko, you will meet Aiko’s spirit and she will make you choose between three choices:

  • I will stand by your side
  • Others need my help
  • Kagerou must pay

These three choices are connected to the three different endings of the game. At this point, choosing any of the choices will not affect the ending of the game yet as this will happen after the Shadow Hiroki fight in Chapter 5.
