M of Market
Prompt: Meliodas and Elizabeth with their kids went to the market. Simply that.
The first one Meliodas and Elizabeth—precisely the reincarnation number 13, Elsa—brought their kids to the market, the twins Tristan and Tristina were fully spirited. Despite what Elsa and Meliodas said, Tristan and Tristina wandered all over the market like the curious kids they were. It was similar to Lancelot. Being Meliodas and Elizabeth's—the reincarnation number 106, Liz—youngest son, it was hard to ask Lancelot 'behave'. Just like Tristan and Tristina, Lancelot was curiously wandering around the market. The people thought it was so cute of them, thankfully. They let the kids wander around in the market freely. It was not like the kids went conquering, after all.
They could not entirely say the same with the other four children, regretfully.
Being the Mermaid, Merissa could not even leave the sea and was stuck in the Oceanus Kingdom. It was not like she did not know what the market was. In the Oceanus Kingdom, there was a market as well. Not to mention, when Merissa went to the 'land' to check on her family, she could use magic to change her tail into a pair of legs and she could walk around the market with her siblings or one or both of her parents.
Not that she could do it for a long time, though.
Unfortunately, her human legs got tired easily and she could not stay on the land outside the building for a long time due to her blind eyes. Unless she wore sunglasses or a wide parasol to block the sun.
Usually, it was Meliodas or Tristan who would need to carry her back to the house.
Otherwise, she would refuse to go back because she still wanted to have an adventure a.k.a. having a light trip around the market. Still, Merissa had no idea about how did it feel to wander around the market with her parents in her childhood.
Merissa smiled and waved her hand "Oh, come on. Don't make that face. I'm not alone in this".
If you asked Lily, she only would smile and answer "I lost my mother in childbirth. Should you ask me whether I have ever experienced how it feels to wander around the market with both your parents?".
...
Okay, let's stop the dry talk which could have made us cry.
Back to the main topic. Although she didn't get the chance to spend her time wandering the market with her parents like Merissa, Lily had fun wandering around the market with Dahlia and her sons, Oberon and Elias.
At least, Melody still had the chance to wander around the market with her parents (well, when they were still alive before the tragedy happened, that was it).
So, how about the oldest daughter who was being unborn for a while, Guinevere?
Guinevere was only 4 years old (physically, plus mentally still stunted due to not fully awakened yet) when she was living with the Sins and was still using the name 'Gwen'.
After Merlin adopted her, it would be the first time she wandered around the market with the Sins.
Holding her dolphin doll, Gwen blinked her round eyes curiously "Market?".
Meliodas offered to carry her considering how the children around her age were still having stubby or wobbly legs and had difficulty walking around for a long time "Uh-huh. We will go to re-fill our daily necessities. Wanna go looking around the market?".
She looked hesitant and curious at the same time. Nervous, even.
Looking at her, Escanor encouraged her "What's wrong?".
Gwen asked innocently "What is the Market?".
Ah. Considering that Gwen had once lived in the Cameliard Kingdom as the sole princess, no wonder she never left the Castle and still did not know what the market was. After Merlin had explained what the market was, Gwen's eyes lit up in curiosity and she nodded her head excitedly.
It was cute.
Gwen was a curious child. She would point or stare at the things in the market which made her curious but fortunately, she was not the disastrous type. The proof was, that she would not touch the things in the market as Tristan or Lancelot did. For that, Meliodas was grateful.
Carrying Gwen on his shoulders, Meliodas looked up at her "Do you have fun?".
Gwen nodded her head and beamed "Um! I like wandering around the Market with everyone!".
Meliodas chuckled, holding her thighs "Nishishi! You can always come with us when one of us goes to the market, then!".
When they were mature, it would be a nostalgic, endearing memory.
