Transmigrator Meris Fano arrives in the Harry Potter world, becoming the only child of the Fano family (maybe) and bringing a System along.
There are just a few small problems: Meris has never read Harry Potter and knows next to nothing about it; the System seems to have no emotions and never speaks to him; and then there's the Fano family... With the System's help, Meris quickly gains an extraordinary reserve of magic and knowledge before turning eleven, along with a wand. But Meris discovers that the Fano family may not be so simple. The wand he gets when he starts school doesn't even come from Ollivander... Unseen, an invisible storm closes in around Meris.
What will happen next?
(The protagonist will have two wands. There is no female lead in the main story; ship whoever you like, I don't mind. A rigorous Harry Potter story following all seven books, with a tiny bit of Hogwarts Legacy content. The pacing is slow. The protagonist is in Slytherin. The first two terms move faster, but once Harry starts school, the pace slows down. Please don't complain if it's not for you. If you don't want to read it, remove it from your bookshelf. Don't mess with my head.)
