The highschool heiress has a 10 y.o. bodyguard that loves Yugioh cards and inflicts over-the-top collateral damage with his gadgets and attempts to defend her.
It's a dumb gag series that doesn't diverge from the formula much. It reminded me a little of Full Metal Panic? Fumoffu with the eccentric bodyguard in highschool, but I didn't find it as entertaining. The art wasn't great either, but it was mostly the humor failing to land dragging down the rating.
Don't tell anyone but I kinda enjoyed it lol. I find Shugomaru funny with how he's so childish and dumb and the over-the-top outcomes got a chuckle out of me usually. The special add-ins for the manga to fill in the pages were really charming too. But it seems like VIZ didn't really edit this collection that well. One page from a previous chapter is reprinted in another chapter. I get why VIZ wouldn't want to spend too much time on this series as they're only doing this as a requirement but it still sucked to see that happened due to poor oversight.
