After beating up Nocrose, Beel and Laventa continued their fighting. As for Elena, she started to support Beel's subordinates who were fighting against the people that the two overlords had brought with them. She did not do much but just supported them with her powerful barriers.
Actually as both sides had almost same numbers and similar level of strength, even the little bit of help from Elena was able to tip the scale of the battle. So Elena did not really worry too much about them and started to watch Beel's fight with interest while continuing to keep an eye on the children who were going through the awakening process.
