[Yu-Gi-Oh!] Can You Ritual Summon Without a Ritual Spell?

I like blue cards, especially Ritual Monsters.

My first deck was Nekroz, and later I played Drytron, too.

Even in an era when the ace monsters are all in the Extra Deck, I still like the ones in the Main Deck, even though they clog my hand every day with five big blue monsters at once.

**

I like blue cards, and not just Ritual Monsters.

I fell in love when I saw that card, and built my only Link deck for him.

Then I got destroyed by a card called Branded Fusion.

**

I like blue cards, even though, strictly speaking, these cards aren't completely blue.

But mermaids and the sea are blue, no matter how you look at it, and I love those powerful, beautiful women.

I even forgot the Ritual Monsters who had kept me company in my deck for so long. But at least, during that time, I truly loved Fusion.

...Until the woman I loved and I were separated by life and death.

**

I've come back to play Rituals again.

But there aren't many blue cards in my deck. There's a little red girl, a golden woman, and a white-haired old man.

Oh, that scary-looking guy in armor with a sword in each hand is the Guardian.

Wait, something seems off.

Why can I suddenly see the physical forms of the monsters I use?

Told in first person. A Yu-Gi-Oh! OCG setting, mainly the Branded storyline. Card spirits from other decks make guest appearances because of the heroine's ability, and most of them are Ritual Monsters.

As for the male lead, you know who it is.

There won't be much actual romance. It's mainly commentary on card art, storylines, and card lore. There will still be a certain amount of story background and plot development.

Theme: A dream-girl story, but not a very dreamy one.
