@RaijinslayerNo probs.
What I'm trying to point out is that:
Normal humans can be sensed by vampires so as espers and magicians.
Since Akira is a haemokinesis esper, it is natural that he emits more AIM and haemokinesis esper's blood flow is weird. Like in a sense Kuroko can see masses, Misaka can see bioelectricity, Ria can tell the volume of water/gas/ice, density, pressure etc. We call it the natural ability of an esper, the benefits that comes with their abilities. However these benefits in some cases can become disadvantages.
The higher the level of an Esper, the more they emit AIM. Which in this case is like having more profound presence compare to his teammates. The main factor in his case is blood since using blood makes a vampire hungry and stimulated.
Tsumiki is also here so he is the only person who emits more AIM than Akira.
Naruto has chakra
Hunter x Hunter has nen
Bleach has reiatsu
Fairy Tail has magic
In to aru our energy reserves depend on personal reality; capacity to how much we can think. AIM is the thing that we emit.
Also keep in mind the vampires I'm using doesn't use magic, at the very least never. Just raw power.
We're going to keep the arcs in a slow pace. After I did state that 3 arcs will take 2 months to finish.
