It just drives me mad when i hear some lound whispers like vaccume cleaner from hitoriki and then see her hyper armour and unblockable attack. The champ is so much ******** and the sounds are most annoying part of gameplay against sakura. When i need to think bout my strategy and i am disturbed by that only one sound.
She's actually just a girl scout trying to sell you cookies but she's very shy so she whispers most of her words. Her axe is only there for self-defense in these dangerous times.
As for Yato... yeah, that guy's a genuine serial killer cosplaying as an 80's glam rock pop star. If you see him don't approach him. Report every sighting to your local Lawbringer and let them do their job.
