Given how Ida reacts during the course of the game, we see him being callous towards not only the player characters, but also all the NPC's. He has no interest in saving anyone and wants to force a new loop (A universal reset to start over and try again.) If we think about his actions under the lens of a RPG player, we can see a common thread to his thinking. Ida was moving through the motions until he put his Tomi into an android and she rejected his plan to put her mind over that loops Tomi. He saw the decision he made as a mistake and wanted to loop to try again and put Tomi directly into the human host instead of an android body. Many would wonder why he did not just delete his Tomi and start over, but that was not his goal. He never wanted to hurt Tomi directly.
In his mind, going through a loop is akin to a player resetting their game or loading a save file. When a player fails a luck check or choose the wrong dialogue option and get a suboptimal response, they often reload the game to try again. See if their luck pans out better or try a different dialogue tree to get a better outcome. In many RPGs, it is possible to romance characters and create couples. Players will often game the system to make sure their preferred pair happens. By making sure all events for that character is seen to giving thousands of items to said NPC in hopes of swaying the numbers into their favor.
This is how Ida thinks. He sees the loops as resetting the world, resetting the game. As if he is loading from the last save point and trying again. Ida is a player. A person who save-scumms through a game to make sure every encounter, random chance, decision is 100% controlled for and exactly how the player wants. He is representative of how real-world players often play RPGs.
Answer: it's Megumi. Waking Juro up. Of course she would want to make a "good first impression". The other thirteen are probably already fully clothed.
