Boss trial event sealand.jpg

A 6 day Boss Challenge event. It's kind of like the Kyonshii Imouto event. It also retells what happened during Ootakemaru saga/Sealand Invasion events but from the perspective of Ootake, Kujira and Kani. So if you weren't around for those events, this is nice way to get a quick recap.


Illusion Boss

Fight a 3 round boss to farm gems used to upgrade stats and skills for the Sealand generals. There's 3 difficulties, costs Sushi.png6 AP to do and there's no time limit. Can be challenged 20 times per day.

Boss Challenges

Fight the boss onmyouji for an area within a 24 hour period. Everyday 1 boss will be available, they can only be challenged 3 times per day, costs Sushi.png20 AP to do and there's a 3 minute timer. Despite the 3 challenge limit, there is a practice mode. You can do practice mode as many times as you want but your score for damage dealt will not be recorded and will not count towards ranking. The fight itself is like of day 7 of a boss defense/vanquish in super oniou/uber event. In other words, the bosses cannot be KO'd so you're goal is to simply do as much damage as possible within the time limit.

The bosses for each area are:

  • Yaobikuni (Arakawa River)
  • Shuten (Mt Oe)
  • SP Shuten (Mt Oe)
  • Seimei (Heian-kyo)

There is guild ranking. Ranking is based on total damage dealt to all the bosses by the top 40 players of a guild. Rewards will be listed below.

Sealand Generals

In this event your onmyouji will be replaced by Ootakemaru, Kujira or Kani Hime depending on who you have selected in this tab. Each of them of have 5 total skills. Ootake and Kani get 2 new passive effects, while Kujira has all his skills except his defensive normal attack. Their skills are not exactly the same as their regular ones so make sure you read them carefully before using them.

Like onmyouji they have 3 active skills, their normal attack + 2 changeable skills. To increase their stats and skills, you do it they same way you would increase an onmyouji's totem, but instead of souls you use gems obtained from illusion bosses. The upgrades are also shared with your guild. So to max out the skills, your guild must work together to upgrade the same Sealand General/s.

Recommended Sealand Generals to level up are Kujira and Kani.


Since this just a short recap event, will only provide a tl;dr of the skills instead of full translations.

Again, these bosses can only be fought 3 times per day. So avoid using a team that relies too heavily on rng and remember to test your team in practice mode first.

SP Shuten is particularly difficult due to him having Scarlet and hitting very hard. Attacking him directly is out of the question unless you want your shiki to die quickly. So what you must do is link Ushi's doll to SP Iba, then do the same with Kosode's needle and hope her needle also links to SP Shuten. Regardless of which Kiyo you use, she must be set to only use her normal attack.

Seimei is even more difficult. At the start of battle he'll use his shield that breaks within 1 hit. So when it does break you're entire team will take a big hit to their HP. The next threat is Inugami with Scarlet, there's 2 ways to deal with him; 1) use Hannya and someone with Dawn Fairy to constant push his move bar, 2) use a Ushi + Kosode team and completely avoid attacking him.
