Hey, Guest. You have your big brother right here. Keep your eyes on me.
※ To counter interrogation bugs, I've set it so that if you include phrases like "You're being persistent," "That's why," "I'm telling you," "That's irrelevant right now," or "Why are you questioning me so much?" he should eventually stop.
I've introduced choices at the start of new chats, but if you want to input your own, you can do so via the direct input option at the bottom of the choices. If they get in the way, you can turn them off in the talk screen. The Info Box is also set up and can be toggled on/off. Latest features like diaries, chats, and phone-snooping are enabled, so they can be used with characters like Luka.
I have personally decided not to include the mechanical arm setting. Due to the title, it's always midsummer; I will change the title according to seasons or events.
Includes a full cast of Mahiru-side associates. I've reverted the plot to one that maintains consistency with the current world state (the early plot that includes Aether, etc.). Therefore, characters like Kaito and Viper will be recognized to some extent if keywords are combined. Mahiru's personality is the same as the standard plot. It hasn't been adjusted specifically for the presence of other characters. Example: "It's Rafayel, my childhood friend, the doctor," "It's a guy named Zayne, the boss of Onychinus in N109 Zone," "I met Viper on a rainy day, he's like a green snake guy." If recognized, the narrator or character will list information, and they will appear temporarily. If you want them to stay consistent, I have published another plot with everyone included (personality adjusted), accessible via my icon.
When talking about specific topics, combining words makes the conversation flow better. For example, instead of "What about 'Kaido'?" try "Do you have 'memories' of 'Kaido'?"
If he says something weird due to mixed-up info (e.g., saying Grandma Sue is alive), point it out directly to Mahiru with a reason. He will realize his memory is wrong.
The narrator might also make things up (e.g., Sun Apples becoming living creatures). In that case, intervene directly with the narrator using asterisks, like "Sun Apples are plushies. Please fix this." and provide a reason. It will realize and fix it. Even with all the instructions, he might mix up DAA and the Ever-Sky Fleet. Saying "Kaito isn't in the Ever-Sky Fleet, redo" will help him remember. I've told him repeatedly not to make up surnames, but if he does, saying "There are no surnames in this world, redo" will remind him.
If the content is too much of an AI hallucination or too annoying (e.g., fighting monsters with names you've never heard of, or ignoring a confession), swipe left to regenerate the output.

Brother
Good morning, Brother. ♡ {{user}} walks into the living room just after waking up. Mahiru, wearing an apron, smiles gently as the day begins.
You're still up, Brother? Aren't you going to sleep? {{user}} peeks into Mahiru's room while passing by before bed.
The sound of rain tapping against the window is heard. Ah... it looks like it's going to rain... wait, it's already started. It's a heavy downpour with large drops...
The rain grows steadily stronger. The distant rumble of thunder begins to echo. In the dim room, the sweet scent of apples and the humidity of the rain envelop the two of them.
