How is this idea: Anime Affectionate Parody/Deconstruction

I'm planning to write a light novel-ish story and this is the basic outline of my character/narrator and the plot.

The Narrator (I can't decide his name) is an Ordinary High-School Student in his first year of high school. He says that he lives with his parents, who are normal as well, and never had anything special happened to him, except that he has an ability to replicate any item he has complete knowledge over (see Is My Character Broken? for details), an ability he hides from everyone including his so-called parents. He's extremely snarky and Genre Savvy, almost to Deadpool level. He was having a normal life (well according to him) until a New Transfer Student comes (which he causes him to go Oh, Crap! and hang a lampshade). She tells him that she is from a commitee devoted to protect and train a magician like him, which he, even though he fully comprehends such thing, tell her to get lost, telling that he just want to have a normal life.

Then few days after, he gets attacked by another magician, who put flesh-eating demon inside his body, leaving him to die. Then the Kanae (current name) comes and offers to save his life  ^{click for details}

, if he chooses to join the Association, which he grudgingly accepts. The plot kicks in.

What I'm planning is that having the story first go very Tropperific and have the Narrator lampshades the living hell out of everything.

As the story goes on, however he becomes more and more unwilling to involve himself with the Association. It will also be revealed that he is an Unreliable Narrator; his parents got killed when he was young, (which made him pyrophobiac) and he just wants to have normal life, not because magic and everything is annoying, but horrifying to him. Once he accepts that he cannot run, he becomes a cold Byronic Hero who becomes more than willing to find whoever is responsible for his parents' death.

Even then he is a coward who runs away when his enemies are out of his league, which forces everyone else in the Association to take care of them. Eventually his cowardice causes Kanae's death (at that point though, the demon is completely eradicated).

After her death, he begs the Association to just let him be. When the Association refuses, he starts to refuse to accept the very experience with it as reality, and forces himself to accept the normal life as if nothing happened at all.

Ultimately, realizing what the Association and his Nakama he met inside there meant, he returns to the association.

That's what I have planned so far. What do you think? Ask me if you need some more details.

It sounds good. As usual, it all depends on the writing.

Excessive Lampshade Hanging can be bad. It's okay every now and then, but too much and it just feels like the writer is saying "Look! I'm aware of this trope! Look at how clever I am for pointing it out!"

I do like his cowardice causing real problems. It's refreshing to see a hero with actual flaws to overcome (instead of what most writers do, which is give them a "flaw" that never actually causes any problems).
