I Was Reincarnated as Someone's Mana??

My name is Magnus Karlsson, and by a series of rather unfortunate events that I had absolutely no say in, I was killed and reincarnated. In this story, you will follow Magnus as he tries his very best to survive in a world that's been thrown into chaos, together with the man whose mana he is, Allan Woodsworth. Well, not a man per se, more of a little boy who has no idea what the fuck is going on, but, you know... I'm sure it'll be fine. Nothing bad will happen to the pair. Nope. No abandoned kids here. Anyhow.  The world that Magnus has been thrown into is one perversed by the will of a great mage who, three thousand years ago, decided that it would be a great idea to infuse all the people of the earth with so-called "orbs". These magical crystals allow their handler to control and generate mana, which they can then use to become mages. Most barely use them, since the mana cost of doing such a little thing as a fireball spell is absolutely ridiculous. Said mage, Theodore Cromwell, Magnus used his resources to infuse not only humans with orbs, but animals as well, giving rise to what the mage community calls "horrid perversions of nature", but what the common folk calls "monsters". Orbs can be used for much, and it is through orbs that people keep track on their level of mana and such, and destroying the orb of a monster is A, the only way to kill it and B, a good way to absorb extra mana and raise ones level.  It is such an orb that Magnus has been tranformed into.     ------ To those that care, I'm very sorry about the title, it's just that, well, it's very good to be blunt about isekais like this since people such as myself search precisely for this, so having super-serious names like "The Magnus of the World of Orbs" would turn people wanting a simple and fun isekai off.  I hope you give this story a fair chance! ------ Edit: IWRASM now has a deviantart page!!! https://www.deviantart.com/thefunartcorner
