Two stories about Leaf cover different professional identities. The first, from 4Gamer's Weekly Pro Gamer File series, profiles Leaf as a 23-year-old top laner for Arneb in the League of Legends Japan League. He is known as the 'Tank Craftsman' and specializes in late-game tank champions like Sion and K'Sante. Leaf cites Evi as a player he respects. The profile notes that despite rarely taking the spotlight, Leaf is considered a key pillar of one of Japan's top League of Legends teams.
The second story, an Anime Herald interview, focuses on Coatsinkleaf, an artist who turned convention tabling into a full-time career after graduating in June 2023 and failing to find traditional employment. Coatsinkleaf started by selling stickers at local Chicago conventions, then expanded to out-of-state and international events, closing 2025 with 31 conventions. He credited his early success to fan art for Hollow Knight, a game he discovered through a friend in college. Coatsinkleaf also detailed his origin in ribbon collecting, starting at Youmacon 2023, and cited Great Pretender and Witch Hat Atelier as favorite anime and manga.
