child gudako fanfic

This is my very first crossover. It is inspired by Fate Grand Order and numerous crossover fanfictions I do not own nasuverse or Rising of the Shield Hero. ++++++++++++++++++++++++++++++++++++ Ritsuka Fujimaru or known as Gudako is the master of Chaldea who managaes to fix the singularities and the lostbelts. However she is tired with the shenanigans of her servants especially due to an accident with the rayshift where she fuses with Hakuno Kishinami(Female). Along the way she noticed she is able to call her female servants making use of her body as a carrier of sorts without using a command spell for female servants, genderless and a few of the male, strangely the rest of the male servants are unable to be summoned without the command seal or being transported the normal way, she could also use her servants power and even fuse her body with theirs making their parameters increase depending on their bonds, but strangely she can only fuse with some of the servants, specifically female servants, gender confusing servants, and a few exceptions. On a rare vacation day she is offered by Merlin a vacation in a timeline where she doesn't have to worry about singularities or any time anomalies. Althought doubtful and suspicious she accepted due to the persuasion of her servants who ussually accompany her due to believing it would be a honeymoon of sorts. While carrying Fou on her shoulder and with Mash at her side she walks to the portal which Merlin opens with the help of a certain someone, who is actually Zelretch Kischur Zweinorg the Nasuverse's biggest TROLL. Not knowing Gudako the fact that Zelretch and Merlin decides to pull a prank on her, she passes the portal somewhat worried because of the chance of vacation coming from Merlin with some feelings of anxiety. After passing Mash is instantly forced to enter Gudako's body while Fou remained on Gudako's shoulder, and they are thrust into a world while there is no singularity or the likes. It is in danger, in fact Gudako winds up in the middle of the ancient hero summonning along with 4 other people and Fou on her shoulder and a note in her hand from Merlin. What will Gudako do in the middle of a hero summoning ? Will she and Fou maul Merlin with unseen ferocity ? Will she disrupt the balance of the world ? How will her servants react to the so called 'heroes' ? It depends on my inspiration and decision ++++++++++++++++++++++++++++++++++++ Updates are not guaranteed it depends on rating and my free time. ------------This message is from Gudako to Merlin "MERLIIIIIIIIIIIIIIIN!!! When I get my hands on you your going to experience a full course of hell by Noble Phantasms!!"
