The first thing they had controlled together was the amount of energy Mika was now able to draw from Alanis' energy reserve.
Since Mika now only fought using Alanis' energy to improve the efficiency of his movements and to protect himself from the blows he could receive when fighting creatures, the amount of energy he could draw from Alanis' energy was something crucial to him.
And when Mika had realized that he could absorb more than double the amount of energy he had been able to before, he had looked at Alanis with concern but Alanis had just shrugged and even told him that if this time the amount of energy he could use had doubled it must have been because of the increase that his basic energy reserve had just undergone.
Mika had been immediately reassured, he had almost forgotten this point and now that Alanis could increase his energy reserve at will thanks to this new spiritual energy he wouldn't hold back either to draw energy from his reserve.
