Synthesized from 2 Yomimono stories · updated Jun 16

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.

The two stories do not connect Leaf the pro gamer to Coatsinkleaf the artist. They are separate entities sharing a name, covered by different outlets on different dates. The dossier reflects only what each story establishes about its subject.
