Cthulhu and the masked demon beast have a synergistic look, and I just wanted to come up with the combo of ↓ and try it out, so please forgive me
It's not related to the main story, so it's omitted, but the original extras are the future emperor and chain, and Outer Entity Azathot and Niarra.
There are no Masked Beasts or Cthulhu in the Deck category...! ?

Strength

First, get the parts with a card car or 《Mathematician》
Please note that you need at least 3500 LP.
The combo parts are 《Carboneddon》in his GY, Synchro Fusionist and Fusion, Re-Fusion, or 《Instant Fusion》in his hand.
Example: Fusionist in hand, 《Carboneddon》in Refusion/GY
First, use "Carboneddon" to special summon "Galaxy Serpent", summon Fusionist, and S summon Nijiko.
Search for 《Instant Fusion》with Fusionist
"Instant Fusion" to fusion summon Norden, the effect lifts Fusionist and X summons Emeral with Norden and rainbow light
S-summon Rainbow Light with Serpent and Fusionist by cutting Noden with Emeral
Search Fusion with Fusionist, Fusion with Rainbow Light and Emeral to Norden, Catch Fusionist with Effect, Advanced Ritual Art with 2 Rainbow Lights and Hellraiser Search
Activate the refusion that you had in your hand Revive Noden, catch Serpent with effect, Summon Kutogua S with Fusionist and Serpent
Second fusion search with Fusionist, Summon Chain X with two Nordens, Death Guardius on top of Deck with chain effect
Revive Norden with Refusion, Catch Fusionist with effect, Summon Emeral X with Norden and Kutogua, Draw 1 with Kutogua effect
Catch Serpent with Emeral effect, Summon Balmunk with Fusionist and Serpent, search for the last re-fusion with Fusionist
《Advanced Ritual Art》drops 2 masked monsters from the Deck and Hellraiser descends, becomes the future emperor with Emeral and Chain, opens a space and activates refusion to revive Norden, catches the masked monster that was dropped in the ritual with the effect, Norden and the masked monster to release Death Gardius as Special Summon
With this, the lineup of Death Guardius, Hellraiser, Future Emperor, and Balmung is complete.
I wanted Death Gardius and Hellraiser side by side, no regrets

Weakness

If it is interrupted even once, it will be inferior at once
All kinds of meta

Customize

I think these Cthulhus can do various things if they get rid of the masked monsters.
Please let me know if there are any holes in the combos or if there are other better combos
I appreciate your advice
