Swords can be assigned to complete chores around the Citadel using the Internal Affairs menu (内番). They do not gain experience points but may gain 1 point in a specific stat at the end of their tasks (see below).
There are three tasks available:
- Horsekeeping (馬当番): Has a chance to increase Mobility or Scouting by 1.
- Fieldwork (畑当番): Has a chance to increase Leadership or Impulse by 1.
- Sparring (手合せ): Has a chance to increase Survival or Impact by 1.
Among the six stats above, the only way to increase a sword's Survival and Scouting stats is by doing Horsekeeping and Sparring in the game. The remaining four stats (including Impact, Leadership, Mobility, and Impulse) can be maxed out more quickly via Refining. Once those stats are refined to their maximum, they cannot be increased via Internal Affairs.
Each task must be done in pairs with another sword, but not all tasks need to be filled in order to start Internal Affairs. Once started, your swords are locked into their task for 20 hours1, but are still free to go to the Front Lines and travel on Expeditions. However, they cannot be on a Kiwame journey or sortie to Special Investigation events. The game will also randomly select one Internal Affairs task and will show your characters chatting about their work. If the task selected is Horsekeeping or Fieldwork, the swords will wear their internal affairs outfits.
Every character has generic dialogue lines for each of the three Internal Affairs tasks. However, certain sword pairings may cause a special dialogue to occur between them.
At the end of 20 hours, a summary screen displays the results of Internal Affairs and which stats were increased for each sword if any.
Note that the game will pick which stat to increase randomly, and even has a chance of failing to increase the stat at all.
Special Internal Affairs Interactions[]
These are unique interactions that may be seen when pairing certain swords together. These lines are different from their default dialogue for each task; those quotes may be viewed on their individual character pages.
Solar Term Background Harvest Items[]
Starting from July 2018, seasonal harvest items can be collected through Internal Affairs tasks to exchange limited-time seasonal backgrounds from Solar Term Background Series.
Special items of Composts (collected from Horsekeeping) and Fertilizers (purchased from the Shop) can be used to increase the number of harvest items gained from Fieldwork.
