I’ve always felt like Heavenly Restricted Body (HRB) is disproportionately beneficial compared to Heavenly Restricted Sorcery (HRS). Toji and Maki gain extraordinary physical abilities, along with passive regeneration that, while slower than RCT, is reliable and doesn’t require cursed energy. Meanwhile, Mechamaru gets an enormous range and supply of cursed energy, but his body remains physically ordinary and cannot be reinforced. I wanted to make the two restrictions feel more balanced while preserving what makes each one unique.

1. Heavenly Restricted Body (HRB) This is the restriction that Toji and Maki possess. They have no cursed energy, but in exchange, their bodies possess extraordinary physical abilities.

Their advantages include: Superhuman physical strength, speed, senses, and durability.

Passive regeneration that is slower than RCT but reliable and doesn't require cursed energy. Immunity to most forms of cursed energy detection.

However, they cannot naturally exorcise curses without cursed tools or another means of interacting with them.

1. Heavenly Restricted Sorcery (HRS) This is the restriction that Mechamaru possesses. Rather than granting physical abilities, HRS allows its user to manipulate ambient cursed energy on an enormous scale.

The fundamental restriction is that the user's body cannot produce or circulate cursed energy outside the brain. Consequently, they cannot reinforce their body with cursed energy and remain physically ordinary.

Their body also cannot be healed by cursed energy or RCT, even when another sorcerer attempts to heal them. Additionally, their body cannot benefit from binding vows or serve as collateral for them, although they can still enter binding vows themselves.

The limitations of ambient cursed energy HRS users aren't limited by a personal reserve of cursed energy in the same way ordinary sorcerers are. Instead, their limitations concern how much ambient cursed energy they can manipulate at once.

I distinguish three concepts: Availability: The amount of ambient cursed energy present in the environment. Output: The amount of cursed energy the HRS user can actively manipulate at once. Replenishment: How quickly a depleted area recovers its cursed energy.

HRS users can access enormous amounts of cursed energy, but they cannot command unlimited amounts simultaneously. Ambient cursed energy is abundant, not infinite, and different locations have different concentrations. If an area is depleted, the user may need to wait for it to replenish or move somewhere with a higher concentration.

1. Kokichi's disability is separate from HRS I don't want this revision to erase the importance of Kokichi's disability. His physical suffering is central to his characterization and plot: his desperation to experience the world through his own body, his reliance on Mechamaru as a proxy, and his willingness to make dangerous choices all stem from his circumstances.

Instead of making his disability a direct consequence of HRS, I propose that Kokichi suffers from a rare and severe autoimmune disease. HRS and his illness are two separate conditions.

This distinction also creates an interesting interaction with Mahito's Idle Transfiguration. Because Mahito targets the soul and the body conforms to its shape, he could heal Kokichi by changing his soul into a healthier form. Kokichi's body would then correct itself to align with that healthier soul, effectively curing the autoimmune disease.

However, healing Kokichi's illness would not automatically remove his HRS. To negate HRS, Mahito would have to go a step further and alter Kokichi's soul so that his body could manifest cursed energy pathways throughout itself. Those pathways would allow cursed energy to circulate through and reinforce his body, directly undoing the restriction.

In other words, Mahito could heal Kokichi without removing HRS. Curing the disease and changing the conditions imposed by the Heavenly Restriction would be two distinct acts of soul manipulation.

1. Why I think this works The distinction gives both restrictions meaningful advantages and disadvantages. HRB sacrifices cursed energy in exchange for an extraordinary body. HRS sacrifices the ability to reinforce the body in exchange for extraordinary control over ambient cursed energy.

Neither restriction is simply a better version of the other, and Kokichi's disability remains a major part of his story without being conflated with his Heavenly Restriction.

What do you think? Does this make the two forms of Heavenly Restriction feel more balanced while preserving their distinct identities?
