Solo Raid
A new special event launched in NIKKE called Solo Raid. As described, "The mode is basically Union Raid but reduced to one Boss you fight, and also instead of fighting it together with your Union, you have to do it yourself." And the more damage you deal, the higher you score on the mode's Ranking — which in turn translates to better rewards.
The inaugural Solo Raid event ran from May 10 to May 18, featuring Mother Whale as the boss — a character introduced in the Chapter 21 update.
Here's Mother Whale in its full glory:

Solo Raid explained
Solo Raid is split into two modes: Normal and Challenge.
Normal Mode
Normal Mode is very similar to Union Raid — you have to kill the boss 7 times in total. You also get 3 entries per day and each entry allows you to attack the boss with up to 5 teams (and obviously, your characters can't be reused).
For killing each iteration of the boss you receive Batteries, but keep in mind that apparently if you can't kill the boss with one entry (so 5 teams), you won't be able to progress to the next level. Also, once you clear a level, you can sweep it to also receive some batteries (but only 1-2).
Each of the 7 iterations has different stats (1 is the weakest, 7 strongest). The table below shows the HP stats so you can prepare easier:
| Stage | Level | HP | First Clear reward | Sweep reward |
|---|---|---|---|---|
| 1 | 55 | 16m | 1x Random Battery | 1x Random Battery |
| 2 | 95 | 40m | 2x Random Battery | 1x Random Battery |
| 3 | 125 | 79m | 3x Random Battery | 1x Random Battery |
| 4 | 145 | 157m | 4x Random Battery | 1x Random Battery |
| 5 | 175 | 234m | 6x Random Battery | 2x Random Battery |
| 6 | 185 | 299m | 8x Random Battery | 2x Random Battery |
| 7 | 200 | 322m | 10x Random Battery | 2x Random Battery |
Challenge Mode
To unlock the Challenge Mode you need to kill the 7th stage of the Normal Mode boss first.
The main difference between the modes is that the formula changes — instead of stages, you fight one Interception-like battle, but instead of one team, you also use up to 5 teams here. Similar to Normal mode, you get 3 entries per day and you can't reuse the same character across the 5 teams. Also, your characters are Synced to level 400, to make this mode a bit easier.
The total damage you do within 1 entry (so 5 teams) decides your placement on the Ranking.
Also, apparently, the entries to Normal and Challenge Mode are separate, so you can keep sweeping the Normal stages for Batteries once you clear it and just focus on the Challenge Mode.
Ranking
Ranking is updated daily and the rewards are sent out once the event ends. On top of the Gem reward you can also obtain unique frames:
The Raid Frame Rewards have changed now, the frames are now given at:
