My esoteric uncle Jules

"The temple is the weakest joint in the oyster shell. Find the right spot and pry it open."
……
There are five layers of history that survive, and one layer that is lost.
Traveling back to the steam-driven Victorian era, Jules discovers that he can capture fragments of a lost history.
And... this world seems to be different from the Victoria in my memory?
[Sixth Historical Fragment: The Sinking of the Titanic]
[In order to complete the sacrificial ritual, the esotericists planned the sinking of the great ship, praying for the God of Hours to look upon it.]
[Objective: Find the secret cultists and stop them before the ship sinks]
[Reward: Ritual Card "Feast of Raging Waves"]
Well, everything is still acceptable, but there is one problem:
Why was Jules selling oysters on the Titanic!
Moreover, how come there is a little oyster who calls herself Lolita and hugs her thighs and calls her uncle?
The steam engine roars with the immortal spirit of the machine, and the dream in mysticism becomes reality.
Invisible arts, secret societies, esotericists...
The world must be messed up, and I'm going to set it right.
……
"Sherlock Holmes can investigate the disappearance of Matilda's necklace, a millionaire can rent a house with a rat in the wall, and the old man next door says someone with an octopus head is asking him to go swimming."
"Then it shouldn't be a problem for me, Jules, to change my profession and stop selling oysters, right?"
Jules said this while holding the little girl transformed from an oyster in his hand.
