Bonny- I don't really know you but rather than a ban hammer, I think I would gift you the ability to hit people with a happy hammer. It will make them smile and be friendly; we already have too much sadness and anger in this world :( so a happy hammer would suit you better
Danmaku- I would gift you a belle maid android who cleans after you and even bakes you pizza which you love so much. More time for gaming and streaming TS ;)
Celestiiella- hmmm you were always the dreamy, out of this world type... I would gift you the ability to go to NASA in Florida and see outer space you can truly be able to view the stars and moon you admire so much from up in space
Deadpool- I wouldn't be able to gift you anything since you break the forth wall too much and can gift yourself something by swiping it D: (hmm maybe some Ajax (Francis) as a gag gift lol?)
Enigma- your name means mysterious or obscurity so perhaps.... the real location of Atlantis or the fountain of youth suits ya
Furval- tsk tsk everyone seems to want to eat you D: i should gift you some immunity from the community who loves to torture you for some exp and lp
Vanilla- hmmm I would gift you a karoke machine, I bet your voice sounds really beauiful when you sing and probably makes people feel all warm and happy inside. Plus I know from your introduction that you love to sing a lot!
