About three hours have passed since they left Yangra. Yuto checked the map in the passenger seat of the military jeep Nguyen was driving.

''We're almost to the enemy's attack point that Theintan-san mentioned, but........''

　The day before they left Yangura, Yuto and the others had received an explanation from Theintan that there was a high probability of an attack in this area. However, this is only our expectation. It's not always the case that the enemy will come as we imagine.
　Yuto understands that, so he always checks his current location and the surrounding terrain so that the enemy can come at any time.
　The main premise of the strategy that Yuto and the others planned for this time was that they would have to pound the surrounding terrain into their heads. And the beginning of the assault would be the signal to start the operation. Yuto checked the radio to be used in that case.

'Shitenji-san, Marion-san, can you check the operation of the radio just to be sure?

Okay.

I understand.

　Yuto switches on the military radio and adjusts the frequency.

'Good.'

I don't have a problem with it either.

Okay. All right, so this is exactly what we talked about yesterday.

　Mizuho and Marion nodded. Then Mizuho turned off the switch and turned to look at Yuto.

''But, Dou Dou Yuuto.''

What?

Are you sure you can't just change the frequency?　I know you don't want your friendly troops to hear it either, but...

'Hmmm, it'll be fine. It's not like I'm dragging my feet, it's just a matter of being cautious. Besides, this is just a way to buy time when you're about to be eavesdropped on. Once the operation starts, the friendly forces can't afford to be concerned about such things... and they're all desperate to survive.

　Yuto laughed, but Mizuho and Marion could feel a part of the air of the actual battle in that Yuto's cautiousness. It is an ironclad rule that those who exchange lives must not lose.

''Also, Du Du Yuto........''

Shitenji-san.

　Mizuho, who was trying to continue the conversation, was interrupted by Yuto.

''Shitendera-san, you can call me Dou Dou Dou or Yuto during the operation. I want to lose as little time as possible, and it's hard to call me by my full name every time, isn't it?

　Mizuho's eyes widened at Yuto's offer.

''Yeah, well, it's inconvenient when you're on a mission!　Yes, yes, it can't be helped........ So, then, Yuto........　That's what Marion calls it, too!　It's about unity.

　Mizuho shook her face widely and repeatedly.

'Yeah, do that.'

　Yuto nods and looks forward to check the radio pack he carries on his shoulder.
　For some reason, Marion's mouth twitched in an uninteresting way beside Mizuho, who looked a little happy.

　And I'm adding the "san" to it.

'Hey!　Marion!　Wow, I thought Yuto had fewer characters than me!　That's it!　I'm on a mission!

Mm ... it's okay. It's only in the middle of a mission (...) and...

Yes, I do!　It's all about efficiency... ha.

　Mizuho looks like she realizes.

''Oh, hey!　Hi.........Yuto!

Yeah?　What?　Shitenji-san.

　Yuto turns around.

'That's it!　Oh, you can call me Mi, Mizuo, too!

'What?　Oh, but ... no, yes, well, then, Mizuho ...-san, is that okay?

Yeah, nothing, Mr....

　While Mizuho was gossiping, the normally quiet Marion interrupted her with a rare bang.

''Mizuho-san (...), isn't it fine?　I'm a Marion, too, and I'm only on a mission...!　And!

Yeah, right, Mizuho-san, I'll take it.

　Marion says to Yuto with a smile, but it was strangely powerful, so Yuto responds as if he were pressured. He somewhat emphasizes that it's only during the operation.
　Mizuho seems to be staring at Marion with a bit of tears in her eyes beside her, but she decides not to pay attention to it.
　Yuto learned how to read the air around here from Mari.

(But what is it?　(Marion's smile ... not soothing ...)

　Yuto returned Marion's muscular-only smile with a weak smile and looked forward to escape.

''Ma, Marion~''

　Marion smiled as Mizuho muttered, looking like a fisherman who missed his chance to catch a big fish.

It's not a good idea to call a girl by her name all of a sudden, so I'm calling her by her first name, too.

"Ma, Marion you are so different...

''Mizuho-san, too...''

"...........

　Two girls whose eyes met.
　There seemed to be a change in each other that only these two could understand.



　Yuto, sitting in the passenger's seat, looks forward to freeze as he thinks he hears a gurgling, onomatopoeic sound coming from the back seat of the jeep. Now, I feel like I should never look back.

(What, what!　There's a fight in the background!　What is it?　(What's being born?)

　With his trembling hands, Yuto decided to immerse himself in the task of looking at the map incessantly.

(Quick, enemy!　Come out now!　Enemy!　(Please!)

　Yujin waits with all his heart for the enemy to attack.
　Suddenly, Nguyen, the driver of the jeep carrying Yuto and the others, started humming.

''No~ I don't mean to be inappropriate during the operation, but it's fun to drive with the younger ones in the car!

　In the same car with the boy trembling beside her and the girls who just wouldn't stop smiling, Gwen was the only one in a good mood and enjoying herself.
