Z is a horrible letter!

I'm sorry, I'm assuming you know what Wammy's House is. Let me explain. Wammy's House is one of several orphanages established by Watari in England. Currently, I can't reveal exactly where in England as the location is top secret, so secret that everyone of these children has their name changed upon arriving at Wammy's House so they cannot be traced after their arrival. Some noted children are L (known as simply L or Ryuzaki), M (known as Mello) and N (known as Near). I now know their true names, but have no intention of revealing this to you, in case you're Kira or know him. 

The main children of Wammy's House, the intelligent ones, the alpha kids as some people call them. Not that many people, but I call us the alpha kids. Some of the alpha kids are dead though, not many.

The alpha kids currently stand as:

Axel

Beyond 

Christofer

Dylan

Emily

Effie (F)

Gale

Hunter

Iras

Matt (Jeevas) (J)

Kumei

L

Mello

Near

Opium

Pandora

Quinn

Rhapsody

Seras

Topaz

Udelia

Violet 

Will

Xion

Yvonne

Z...?

There's no Z. Never has been, maybe could be. Some day, hopefully. I guess you've probably guessed that we're called the alpha kids because, as much as we're the most intelligent kids of Wammy's House, our aliases are all based off a letter of the alphabet. It didn't start like that though. First we had L and then he left to do detective work, sometimes he came back to stay at Wammy's between jobs. Then we had Axel and Beyond, who were second in line to become L, the world's greatest detective. Long story short, Axel killed himself, Beyond got mad because it was L's fault and then he left Wammy's. 

Watari left to look after L and then we got Roger around the same time that Mello, Near and I joined Wammy's. Watari only ever came back if he was bringing another student that he was looking after. There are currently 25 alpha students out of a possible 26 (although there could be more considering that some of the alpha students are dead). The only letter we don't have is Z. I assume, that's why Watari had returned.

"Watari, I take it this young girl is a new addition to Wammy's House?" He nodded in response. "The only problem is there is a serious lack in Z names." She muttered some girl names: "Zizi, Zivah, Zipora or Zina?" Watari pondered on these but then shook his head. "They just don't suit Wammy's" He frowned. "Oh...Z is a horrible letter for names!"

I popped my head round the corner and then revealed myself. "How about Zoe?" She and Watari smiled at this suggestion. "That's a good suggestion, Matt." I smiled. 

So now there's 26 alpha kids. Who knows? Zoe could be the next L...after Mello, of course.
