Prequel. Gaius's/Gaia's life before he chose to reincarnate. In the first chapter, note how he considers reincarnation but decides leave that decision for later, and instead opts to attain power through finding allies.
Is there any Japanese cultural significance regarding the recurring rice-eating gag by Ami and her father, or is it just the author's creative interpretation of "pulling up some chairs and eating popcorn when something interesting is going down" meme?
