General
Event passes are required to participate in the 'Regiment Battle' event. Each sortie uses up 1 pass. The maximum number of passes that can be stored is 3, and can be replenished with 1000 koban. Passes are automatically replenished for free every day at 5:00 and 17:00 JST.

There are 4 maps in this event: Easy, Normal, Difficult and Expert. Oodenta Mitsuyo has a chance of dropping from the final wave of the Expert map.

As usual, clearing a map will open up the next one.

Event Sortie Rules
When going on sortie, the chosen team will be the first to fight. Once on sortie, all 4 teams can be used freely to fight consecutive enemy teams, with the aim to defeat all of them. Every map has fixed day or night battle conditions. *Note that the snow background does not affect battle conditions.

After winning a battle, the following options will be available, from top to bottom, left to right: Additionally, pressing the large red button under the wave counter will hide these options, allowing the player to assess the enemy's formation and scenario to pick out the most appropriate team to use. Pressing it again restores the panel.
 * Continue: Proceed to the next wave with the currently selected team
 * Restore: Use 'Army Provisions' item to fully heal the currently selected team
 * Not available if the whole team is at full health
 * Does not relieve sword fatigue
 * Warning: the game will not ask to confirm your choice, so click carefully!
 * Change teams: Swap your current team out for another team. However, you cannot switch to a team who is currently on expedition.
 * Return to the citadel: End the battle and return to the citadel, taking all collected Fireflies with you.

Note:
 * Once a team has been changed out, that team cannot be used again for the remainder of the sortie, so make sure to time your team swaps carefully to avoid being disadvantaged by the changed match conditions. Do take the time to find a team formation that will be advantageous in battle.
 * Teams participated in the sortie will receive their share of XP upon the completion of the final wave, or upon returning to the citadel. All swords in a team will receive the same amount of XP irrespective of their performance and participation in fights.
 * If your team captain is heavily injured, the 'Continue fighting with the current team' option will be disabled. You can either use the 'Army provisions' item under the 'Restore team' option to continue fighting, or choose the 'Change teams' and 'Return to citadel' options.

Fireflies
Defeating enemies during the event will yield Fireflies, which can be collected at the end of the sortie or cashed in earlier than usual by returning to the citadel between matches. Completing the entire sortie will also apply a small multiplier to the amount of Fireflies collected that scales with the chosen map's difficulty, though being forced back to the citadel due to losing will only yield 30% of the total count.

Note: Having Hotarumaru on your team will increase the amount of fireflies obtained by 1.5x. This only applies to battles he has participated in and does not apply to the entire map run.

Rewards will be received after obtaining a certain amount of Fireflies. Please refer to the Rewards section for details. The current number of Fireflies collected is displayed next to the event banner.

Special Items
The following items may be used during the event sorties. These items may be claimed as rewards for collecting Fireflies at certain numbers, or may be purchased at the Shop. Army Provisions: While on a Regiment Battle sortie, this restores the health of all members of the currently selected team, including swords that are no longer able to battle.

Triple Cage: Using this before going on a sortie will triple the number of Fireflies collected.

Saihai:

Note: These items are for the Regiment Battle event only. Once the event ends, any unused items will vanish.

In the Event of Internet Disconnections
During the event, if the game is interrupted due to connection issues, it may be possible to continue playing from where the interruption occurred after logging in again and data recovery.
