I'm Really Not Experiencing a Split Personality!

Congratulations! Your golden finger System has finally come online!

Protagonist: Why does everyone else get a simple, straightforward System that solves everything with brute force, while mine is called "Mind Reading GO: The Gacha Stage, Come If You Dare"?

Did they base its odds on some famous gacha game with a one-in-a-thousand chance of getting a top-tier character and no pity system for years? Surely not, right? Right?!

The good news: Your System has an extremely high ceiling.

The bad news: Your System also has an extremely low floor.

Protagonist: Do I have to draw cards every day? Do I have to change personas every day? Wait, doesn't this System have a refund or exchange policy?

What do you mean my persona refreshes at four every day? Don't normal people divide the day at midnight or noon?

What do you mean I have to win tense, exciting skill-command-card battle minigames to build up NP and unleash my Noble Phantasm?

What do you mean, just when I've finally filled my NP gauge, you change my persona in the middle of battle?!

"What do you mean, if you keep the boss busy a little longer, I can unleash my Noble Phantasm?"

Teammate: Seriously? I'm supposed to hold off an Upper Moon, a Lower Moon, or the Demon King?

Teammate: M-me?

* Tentative blurb. It's about a shape-shifting Servant, probably crossing over with Demon Slayer, plus FGO and Touken Ranbu. I'll see about adding other series later.

* The protagonist's temperament and personality shift slightly depending on the Servant drawn each day. Basically, to outsiders, they seem like they've got a split personality (?).

* This isn't necessarily the final blurb. It may still change before the novel begins.

Theme: Strive to improve
