Granblue EN (Unofficial)さんのイラストまとめ

The rest of the blog preview shows Giyu, Nezuko, and Rengoku, as previously unveiled on Twitter.

The blog promises that more characters from Demon Slayer will be revealed soon!

The art for Zenitsu, Inosuke, and Tanjiro suggests that they will be a trio unit - and the "Kamaboko" file name is a fun little nod to Inosuke's complete inability to say Tanjiro's name.

Mirin:

The new characters will be available until 12/25, and until then we have some new loading screens featuring them.

Nemone:

Some days you are bonker, some days you are the bonkee...

Santa Sariel can be uncapped to 4 stars.

At 3 stars, his stats are as pictured.

At 4 stars, the Dark attack aura goes to 110%, his summon cooldown goes down to 6 turns, and he also inflicts stacking debuff resistance down and atk down/def down on summon.
