In a way, Yurika's suggestion was the same as what Kiriha was doing. She would stabilize Sanae's body from the outside while supplying her with energy at the same time. The only difference was that it would be done using magic.
“So, what can we do to help, Yurika!?”
“Please stand in a circle around Sanae-chan!!”
Wearing her magical girl outfit, Yurika held her large cane and pointed its tip at Sanae. She was currently holding Encyclopedia. The cane she had been using before, Angel Halo, had fused with her clothes in her battle against Maki, and had now turned into a series of decorations including the wings on her back.
“I will then transfer everyone's spiritual energy to Sanae-chan”
“Is something like that possible!?”
“I have never tried, but it should be!!”
Yurika's idea was to activate her magic, at the same time the haniwas run out of power, to maintain Sanae's body for two minutes. Since maintaining Sanae's body required energy, the other six people in the room would supply that energy. Yurika would use Encyclopedia to stabilize Sanae's body while using her own spell to supply Sanae with spiritual energy. This was a bold move Yurika could do because she had gotten another cane.
But because it was such a bold move, it was also a complex spell that required minute control. It would take longer than normal to activate, and she had stopped Theia and Ruth because she wouldn't have enough time otherwise. If she were to try without them the strain on the remaining four would increase by 50%. Since transferring spiritual energy was similar to the energy drain that vampires used, Yurika didn't want to do anything unreasonable.
Koutarou and the others did not feel like anything was off with Yurika about to use a large-scale spell. Since Encyclopedia saw everyday use, they didn't think much of it, and everyone was already aware of Yurika's skill when it came to handling the cane. When they had sent Yurika to drive away a stray cat, she had been able to use supersonic waves to control it.

But in fact, Yurika hadn't gotten better at using Encyclopedia. She was capable of making full use of its power from the start. The reason why it looked like she had improved to Koutarou and the others was because she would pretend to improve while using spells of a slightly higher level. And by repeating that, she was now able to use magic to the fullest of her capabilities in front of everyone.
A magical girl that was just supposed to be cosplaying was really using powerful spells. That unthinkable reality was unfolding right in front of them. But even if it was just cosplay, since everyone believed in Yurika, they bet on her magic. There was no longer any point in arguing whether Yurika was a cosplayer or the real deal. Her courage and magic were real, and everyone knew that.
“Alright! Let's start!”
“Yes! Precast – Energy Converter―”
Yurika immediately begin incanting her spell. While listening to her voice, Koutarou whispered to Sanae. It was necessary to put her in the middle of the room and have everyone else surround her. She couldn't just keep being held by Koutarou.
“Sanae”
“But...”
But the uneasy Sanae didn't try to get away from Koutarou. Instead, she pushed towards him and grasped at his clothes.
“Don't worry. You can trust in Yurika right now”
“Really?”
“Yeah. I'd even bet my treasured bat on it”
“...Okay”
Koutarou's treasured bat was the baseball bat a player known as the God of Slugging had used. Since Sanae knew just how much he valued that bat, she decided to trust his judgement. She separated from Koutarou and floated in the center of the room. Right after that, the remaining six people surrounded her.
“Okay Yurika!”
“We're counting on you, Yurika-sama!”
“Yes!”
Yurika nodded with an unusually serious expression and continued her incantation.
The main spell is Transfer Soul Energy. On top of that, I need three additions to the spell: an invocation delay, expand the number of targeted people by six and extend the effective time to two minutes. And while I adjust the waves of six people through the Energy Converter to match Sanae-chan, I must use the cane's magic to stabilize Sanae-chan's body. Even if I prolong the cast time to reduce the magical power used, I only have one shot... can I do this?
As Yurika went through the procedure in her head, she realized how difficult of a job she had. Her usual negative side appeared and made her anxious.
