All equipment Improvement through the Akashi's Improvement Arsenal require specific "helper ships" to second Akashi. Depending on the ship second to Akashi, its remodel, and the day of the week, the set of equipment that can be improved will change.

- In some cases, an equipment can be upgraded into 2 or 3 different new equipment, with the helper determining the result.
The following equipment do not require any specific helper, and can be improved in all cases where they are not overtaken by other help upgrades, including when Akashi is alone in the fleet:
List of ships and their related quests

- "Improvement" means that the relevant ship can only improve said equipment but not improve it,
- "Upgrade" means that the relevant ship can both improve and upgrade said equipment (on at least one of her remodels),
