Dungeon Village 2

Unlike most of the other games, 'Kairobot' is a job title in this game. You get the job title through picking up trait points from several different actions; gifting, building, completing quests, events, etc. When you give a present, you can see which trait points are awarded by clicking the 'Town Traits' button on the bottom right (do note these are only for 5th page presents). When you build a structure, you can go to Information → Town Traits for the same info. A list of these can be found on Outside Linkthis wiki. (Check structures, events, items, and enemies)

You need to get 10 'Robot' points, 10 'Royal' points, 10 'Cute' points, and 10 'Party' points to unlock the job. You will also need a 5 star town. I'm not sure if the map actually matters or not but I did this on the third map (tropical).

To get 10 robot points, gift 5 'Wind Up Dolls' to an adventurer.

To get 10 royal points, build a castle or gift 10 'Black Tea's to an adventurer.

To get 10 cute points, gift 4 'Dolls' or 5 'Plushies' to an adventurer.

To get 10 party points, host 2 'summer bbq' events.

Once you have it unlocked (it will be 'Kairobot' for a male adventurer or 'Sally Prin' for a female adventurer), you will need to switch someone to that job. It requires they have 10 medals and costs 25 diamond points.

Once one of your adventurers is a 'Kairobot' or 'Sally Prin', you will get the achievement (and basically a demi-god of an adventurer).

You get different 'trait points' based on just about every action that you do - gifting, building, completing quests, etc. These trait points have combinations that unlock titles and usually a reward with it for the first time that you unlock it. You need 50 different 'titles' across all your towns to get this achievement.

When you give a present, you can see which trait points are awarded by clicking the 'Town Traits' button on the bottom right (do note these are only for 5th page presents). When you build a structure, you can go to Information → Town Traits for the same info.

A list of these can be found on this wiki. (Check structures, events, items, and enemies)

You can get 50 titles mostly from the first two towns by following the 'Town Guide Contests' in 'Manage' menu. I skipped a few so it took me halfway through my third town to get it.
