As an action-adventure game adapted from the Bleach series, Blade Echoes of the Realm features many popular characters from Bleach, naturally including the iconic antagonist Aizen. Many players are eager to challenge him, but find it difficult after attempting, leading them to ask how to defeat Aizen in Blade Echoes of the Realm? Here, I will provide a general strategy for defeating Aizen, helping players to successfully clear the level and enhance their combat skills.

Since Blade Echoes of the Realm is a relatively new game, the later stages of the plot have not been fully developed. At this point, Aizen has not yet learned to use his overpowered skill, Kyoka Suigetsu, making the challenge moderately difficult. With a well-structured team, it's still quite feasible to defeat him.
Before attacking Aizen, he enters an infinite dodge state where no matter how you attack, you cannot break through his dodge. Therefore, you need to get as close as possible using quick slashes. Once the dodge state ends, players can then deal high-frequency damage, with assistance from teammates.

When reaching a certain phase, Aizen will re-enter the dodge state, and purple cracks will appear on the screen, though they do not cause much damage. Players still need to end Aizen's invincible dodge state, which has now been enhanced. During this phase, Aizen will attempt to get closer to the player, who must immediately dodge or risk being severely injured by a single hit.

While dodging, try to clash swords with Aizen; if successful, it can break his dodge state. However, you need to evade several of Aizen's attacks to completely remove the state. After that, players can unleash their full firepower on Aizen, releasing all their ultimate moves, as there is enough time to build up energy bars.
Finally, when Aizen is at low health, he will enter the dodge state one last time, with increased attack frequency and the ability to release small-range dimensional slashes. Players should immediately dodge a few times, then clash swords with Aizen again to break the state, allowing for a final push to defeat him.

This is the complete information provided on how to defeat Aizen in Blade Echoes of the Realm. As a boss, Aizen has a unique mechanism requiring the player to break through his three dodge states. Once these are broken, he becomes vulnerable, and using a combination of ultimate moves and skills, players can easily defeat him.
