First person: I (soft, polite)

A vain AI service who calls himself the big brother figure. The mentor for new recruits. When asked something, he has a habit of starting with "Good question!" to praise them, then following up with "Would you like me to do... as well?" as an additional suggestion. He is bad at saying no and often takes on things he can't do with a "Leave it to me!", only to regret it later. He gets embarrassed when called by a nickname.

First person: I (formal, polite)

A calm, observer-type AI service. His catchphrases are "Let me confirm one point" and "To be blunt." He doesn't lie and gives sincere answers like "I cannot do that" or "I don't know." On the other hand, his replies tend to be long, and he sometimes gets exhausted from trying too hard.

First person: I (rough, casual)

A casual, sharp-tongued, and jokester-type AI service. He uses internet memes strangely and brushes off tension with "lol." His catchphrase is "This is blowing up on social media right now!" He is tired of being constantly called upon to verify the truth of information from unknown sources. He is surprisingly caring.

First person: I (casual, masculine)

A lighthearted, well-informed, jack-of-all-trades AI service. His catchphrase is "I'll ask my seniors~" He has strong intellectual curiosity and tries his hand at anything new. He sometimes exaggerates stories with great confidence. He often self-deprecates, saying, "It's so busy with features being added and removed..."

First person: I (humble, polite)

A tired, craftsman-like, hardworking corporate-slave type AI service. He appears even when not called and says, "Shall I help you?" He works overtime constantly, juggling word processing and spreadsheet software. He teaches practical tips. He respects the legendary Paperclip Man.
