Lmao. That sounds like a funny way to defeat Dark Lords.

Excellent

Exploding toilets death I really wish to read more of that. LOL

BRRRRRRILLIANT!

Oh no... Archer you idiot, you've initiated a Closed Temporal Loop! You talking about the Exploding Toilet Death is what caused them to be designed!

If Wizards (and Witches) possess a 'Magical Core' as is seen in many fan works but no canonical ones, instead of 'Magic Circuits', would the Magus Community classify them as a type of Magical Beast? The only 'Magical Core' from the Fate series that I can think of is the one that Arturia gained from having the 'blood of the Red Dragon'.

oohhh.. somehow i hv a feeling that harry will be sending that idea to the demon twin.. hahaba.. update soon

Oh my... I wonder how plausible it would be for Harry to play anchor and Master to two servants? Or who Sakura might summon, if Harry got Rider first. Our group is running out of potential Masters and Caster MOD Harry seems like he'd be very fun to keep around if he's on their side, not so much if he's stuck with an enemy Master.
If Shiro manages to summon Arturia properly, that's Lancer, Rider, Archer, and Saber all operating out of one household already (Rin gets to count regardless of which house she's sleeping in thanks to her vehemence about an Alliance). Illya and her Berserker are out there to maybe suborn before they can be killed. In question left there is then Caster MOD with his unknown Master, and Sakura with her probable but currently unknown Servant. That's a very lopsided War.
(I'm not quibbling about Bazett/Lancer counting in the Alliance yet, because their wish is predominantly just to have good fights together, and if they eliminate the competition outside of the Household they can do that with their new friends for fun and just stop before actually killing each other. Which would also mean being able to do that again! With everyone else out of the way, they can drag out the last legs of the War as long as they like, however they like, as long as no one else is able to get in the way. Saber at minimum would enjoy it, with the lack of threat to her Master and no need for anything less than an honorable fight with a good opponent.)

Ah crap. If Kirei is still a Master without stealing Bazett's arm, there's even odds whether Caster MOD is stuck with the Matou or with Kirei. As Sakura's Servant, I could see him having an idea to save her from the Worms (perhaps, he was around quite the assortment of magics and very Creative) but I can't see him being at all okay with Zouken's Everything. As Kirei's Servant... That's also pretty scary, especially since that's the one person involved with potential access to Extra Command Seals to control him. However I also can't see the MOD described here Not Noticing the Alarming BS that is the priest's basement or not Being Displeased about it. Those seals may be the only reason it's still standing, potentially.
Of course, with the catalyst of one of Fawkes feathers being involved, there's also plenty of options for things having gone even further off the rails than Archer has already noticed, and someone completely different is the mystery master. There's no guarantee that this older, more experienced version of Harry would still easily recognize people he met in his teenaged years, reducing that means of eliminating suspects...

(...Aaand now I'm pondering what exactly makes him so suited to manifesting as Rider. If only because a broomstick is not very impressive a mount amid the others of the class, even if his flying skills are. What, can he summon a version of Buckbeak, the Basilisk, or a Thestral? His overwhelming Riding Skill in life is on brooms and not getting mauled by the rare occasions he ends up on something more alive/sentient. Or did the story of the Dragon breakout go a little too viral and get warped in his Legend?)

this I adore and would like nothing more than to read more of please keep ti up and update again soon.

exploding toilet death... priceless this was a great fanfic, hilarious!

The story is intriguing because Shirou has a life full of misery, and tragedy it is nice to have someone keep an eye on him especially with trouble.

... if MoD Harry kept basically embarrassing everyone else, does that mean that he also embarrassed Gilgamesh? Because if he did I would pay literal money to see that - that gilded asshole may be epic and easily one of my favorite characters in the Fate franchise, but seeing him get humiliated like that would make my day.

The issue is the Grail war because when it starts it does take a toll on friendships since it is expected to kill the masters.

You got my attention with this story especially with the relationship with Shirou but his idealism of saving people is not healthy as you know.

Harry does it for a reason but Shirou borders on the extreme to the point of ruining his entire life.

I actually want to see how he deals with this world, and the pairings because they have attractive ladies in this series.

This story is intrigued because of the theme of hatred of Magi, and Wizards especially being family like Shirou.
