Hakari summons doors primarily as a versatile combat maneuver to trap and restrain his opponents, providing him with a significant tactical advantage in battles. This ability allows him to control the battlefield and limit an enemy's movement, creating opportunities for further attacks or to evade incoming ones.
This technique is a notable aspect of Hakari's fighting style, demonstrating its utility even outside the confines of his Domain Expansion, Idle Death Gamble. A prominent example of this occurred during his encounter with Yuji Itadori, where Hakari effectively used summoned train doors to entrap Yuji. This illustrates that the doors are a fundamental and practical component of his arsenal, offering him a direct way to manipulate his environment and opponents.
Key Functions of Hakari's Summoned Doors:
- Trapping Opponents: The most direct use, preventing movement or escape.
- Restraint: Temporarily incapacitating an enemy to set up other attacks.
- Environmental Manipulation: Altering the battlefield to his advantage, even without a full domain expansion active.
Hakari's ability to manifest these doors highlights his strategic prowess and unique cursed technique, allowing him to surprise and overpower opponents by controlling their physical space.
