illya was right now sitting in seiza position in the living room, in front of her sitting on the couch was her brothers who had continued to scold her for the last two hours , occasionally, shirou would also put in some words of scolding, on the side she could see ange lazily relaxing on the couch watching in amusement ,

the worst of all was that ruby did not stop laughing at her in secret, illya was actually very much tempted to reveal the existence of the perverted stick to her brothers but she then remembered about how the magus normally deal with people who had learned about the existence of magic by killing them of along with their family, she did not want her brothers to be hurt because of her so she stayed silent and continued to endure the verbal lashing , finally after two whole hours she was allowed to go to her room to relax and sleep, but before she left yuuji gave one final word to her

"oh, and illya , for the next two weeks, you are grounded, you will go to school then come straight home, i will inform taiga about the punishment so that she will bring you straight home after school, so do not try to escape your punishment" yuuji ordered to which illya hung her head and said okay while a certain kaleido stick was laughing it's head off,

****************************************************************

after illya went to her room yuuji immediately turned to shirou

"i do not trust that stick that zelretch made, for all i know it may try to use the kaleidoscope to teleport illya out of the house, can you use structural analysis on it ??" he asked to which shirou nodded and said,

"i already did, it was hidden inside her bag and was laughing hard when we were scolding illya, however i cannot counter it's power unless i use a B-rank noble phantasm but it would immediately expose our knowledge of magecraft to illya" he said

"i guess there is no other choice, i will have to make a barrier myself" yuuji said to which both shirou and ange showed surprised looks, they did not know that yuuji was capable of making bounded fields, but in truth what yuuji was about to do was recreate a barrier he made in his previous life, the purpose of the barrier was to stop anyone from using a teleportation device inside it, he had created it previously because he was afraid that the organization might mass produce his technology to equip all it's members, so he made a counter measure, but now that he had access to alpha particles in his body he can easily create such barrier without using any catalyst or device , whenever a wormhole for a einstein rosen bridge was opened inside the barrier, the barrier itself would use another wormhole of the same frequency to counter and cancel the wormhole, in case that the wormhole was too powerful the barrier would reroute the exit of the portal to the same location as that of the entry portal,

after yuuji was done setting up the barrier he also made another portable barrier on illya which was a variation of anti-alpha particle barrier he made in his past life, anyone who was covered in this barrier would not be able to use prana or mana, similarly any attack made of these energies would also be nullified by the barrier , every time anyone inside or outside the barrier tried to use magecraft , the barrier would absorb all the prana and mana making it more powerful, simply put , the barrier made the magic resistance of a saber class servant look like nothing more than paper armor while the barrier was the shield made of divine metal,

while yuuji was doing his work, ange watched him closely with a unnoticeable blush on her cheeks, she was thoroughly impressed at what he was capable of , even a magus from the age of gods was incapable to recreating the things that yuuji was doing, all this made her attracted to him even more,

*************************************************************

a few days had gone by in which things were pretty calm , yuuji was happy to know that both the barriers were working just fine , but what he didn't know was that he had actually forgot to add the anti- kaleidoscope barrier on illya's school clothes so ruby was easily able to teleport illya away from the enchanted clothes as long as she got out of the house which was covered in the space-time barrier,

during the past few days he sensed many fluctuations in mana that ange recognized as the corrupted servants but before he could do anything the mana would disappear, he thought that rin and luvia had finally taken this seriously and started to use the kaleido sticks themselves to retrieve the cards, what he did not know was that the crafty magic stick had found a loophole in his barrier so that illya could fight the threats,

today was also another one of those days where he was spending his days peacefully with his girlfriend, this was another change that had happened, yuuji had actually found the courage to express his love to ange who was so happy could she could fly without using vimana but kept her indifferent face, she had actually wanted to get married right away but yuuji insisted to take it slow so she settled for it,

suddenly he felt a extreme surge of mana in the area much more that when a servant appears,

"that should be the berserker servant " said ange from the couch, before yuuji could say anything he heard the main door to his house opened with force, shirou ran into the house with a panicked look on his face,

"nii-san , i went to luvia's house to talk with her but there was no one there, instead i found this" he said while holding his hands forward in which was illya's school uniform, the enchanted clothes that yuuji had made the barier on , immediately yuuji's eyes widened and understood what had happened, he told shirou to stay put he immediately teleported to the location of mana surge leaving behind his brother and girlfriend,

**********************************************************

illya and miya sat on the ground exhausted, they had just used the parallel install to bring out multiple copies of Excalibur to defeat the corrupted berserker, ring and luvia were also present while talking with each other, suddenly ruby turned towards rin and said,

"so , rin-san , did you find out who put that bounded field on illya's clothes??" to which luvia and rin looked at each other and said,

"the both of us together had tried to track down the spell but we could not, the barrier is extremely complicated , so much so that it would take at least a few decades for us to decipher how it works,further more it was made from a form of energy we had never seen before, it felt similar to mana but it was at least a million fold potent than mana, whoever it was that made this barrier is most probably a sorcerer" she said to the surprised girls,

before illya could say anything a roar interrupted them , when they turned around they found a heroic spirit emerging into the mirror dimension the same way that the saber class had arrived, however this servant looked very different , he wore a black knight's armor with a helmet which a slit from which red light was coming, black mist was emerging from the servant making him look like he was one with the shadows, once the heroic spirit had materialized miyu immediately used install with saber class card however this proved to be a wrong move because

"AAAAAARRRRRRRRRTTHHHHHHHHHHHHUUUUUUUUUUUUUURRRRRRRRRRR!!!!!!!!"screamed the servant with madness
