The "janitor" slander is from admiral twerkers these clowns have habit of downplaying anyone that outperforms their favs even more so if it's character related to marimo lol. To this day they haven't come to terms with fact it was Shiryu who took down garp not Lakazuki equal who was being bullied by the old man until Whiryu stepped up
Shiryu despite one shotting Garp is yet to display even fraction of his real abilities Loda always have to tip toe around these type of characters so they don't overshine the so called captains but his time will come. We already know he is monstrous swordsman very likely that Raiu is supreme grade meito. His df contain a lot of surprising abilities absalom was fodder who couldn't showcase full potential of the fruit for me i do consider him top tier
