"Lacking Spiritual Energy?" Jim and the other four Spirits frowned from those words as realization dawned upon them.
Indeed, Spiritual Energy was a crucial thing for a Summoner like Jasper. Every time they used a skill or summon a Spirit, Summoners needed to have a required amount of Spiritual Energy. How come did they even forget about that?
But well, they couldn't blame themselves as well. Jasper had always had an abundant amount of Spiritual Energy making the other party be accustomed and be complacent that he could perform such skill. The same went for Jim and the four Spirits, they were also expecting that Jasper would not be lacking in Spiritual Energy since the other party had plenty of it.
But never did they thought that their expectation would betray them.
